The PowerFLOW GPU solver is licensed the same way as the PowerFLOW CPU solver — no special or additional licenses are necessary to use the GPU solver. It provides the same physics as the CPU solution, but executable on NVIDIA GPUs, allowing users to run small-scale problems on a desktop equipped with a GPU, or to simulate industrial-scale problems on multiple GPU systems. GPU computing reduces the expense of buying and maintaining a CPU HPC cluster. Generally, one NVIDIA A100 Tensor Core GPU will replace 120–200 CPU cores in terms of performance. Recent releases of PowerFLOW further accelerate aerodynamics and aeroacoustics evaluation of full vehicle configurations at reduced cost with the multi-GPU PowerFLOW solver.
Both can be run on-premise. SimUnit credit licensing is valid for both on-premise and on-cloud compute, providing flexible and instant access to high-core-count HPC configurations — users can solve simulations with their own on-premise hardware or on the 3DEXPERIENCE Cloud. Users can run any SIMULIA solver from a single license pool, on local hardware or in the cloud.
So the customer has full flexibility: they can install and run PowerFLOW or FMK on their own on-premise servers or HPC cluster, consuming SimUnit tokens for solver compute, without any dependency on 3DEXPERIENCE Cloud.
SIMULIA Fluid Dynamics Engineer is a 3DEXPERIENCE role (trigram: FMK) that provides several applications that together constitute a powerful, versatile CFD software package. The key applications included in the program are:
- Fluid Model Creation (geometry abstraction and mesh generation),
- Fluid Scenario Creation (boundary conditions, physics setup, solution options), and
- Physics Results Explorer (post-processing).
Virtually all of this is achieved within a single user interface in 3DEXPERIENCE, with the loaded application automatically switching depending on the context.
The core solution technology is an industry standard RANS-based finite volume (non-LBM) CFD solver.

The role provides a unified environment for pre-processing, solve, and post-processing. Fluid Model Creation allows the user to build high-fidelity meshes for fluid flow calculations, accurately capturing boundary layers and automatically extracting the fluid domain. Fluid Scenario Creation allows the user to define fluid properties and physics/boundary conditions.

On cores: 3DEXPERIENCE grants up to 16 free cores (either local or cloud) for solving simulations. Note that some older documentation references 8 cores as the base embedded compute, with the newer figure being 16 — embedded compute licensing allows routine execution of one concurrent simulation job on 8 cores, or multiple jobs up to 16 cores.

Importantly, meshing and results post-processing is "free" and does not consume credits or require tokens — only solver execution draws from the compute licensing.
PowerFLOW не е пакетиран като единична именувана 3DEXPERIENCE роля по същия начин като Fluid Dynamics Engineer (FMK). Достъпът до него е чрез ролята All Physics Analyst (PXK) на платформата 3DEXPERIENCE, която обединява многофизични солвъри, включително PowerFLOW. Ролята All Physics Analyst (PXK) включва PowerFLOW, с възможност за ускоряване на аеродинамичната и аероакустичната оценка на пълни конфигурации на превозни средства на намалена цена, използвайки многопроцесорния PowerFLOW солвър. PowerFLOW може да бъде достъпен и като самостоятелна инсталация с лиценз за SimUnit compute, без непременно да се изисква роля на платформата. Точната конфигурация на ролята трябва да се потвърждава при всяко използване, тъй като Dassault Systemes предлага различни опции за пакетиране.
PowerFLOW is available both as a traditional standalone product and on the 3DEXPERIENCE platform. For compute, PowerFLOW simulations consume SimUnit tokens and/or credits — available as PowerFLOW Simulation Units in packages of 1,000 or 100,000 units, where the number of credits consumed per hour equals the number of active simulation processes used. SimUnit tokens and credits provide unified licensing usable across the entire SIMULIA portfolio — including PowerFLOW — whether on cloud or on premise. In short: PowerFLOW has its own GUI/client license (standalone or platform-connected), and solver compute is consumed via SimUnits. It is not exclusively a 3DEXPERIENCE role in the way Dynamic Engineer on 3DEXPERIENCE (FMK) is.
In order to request DSLS license keys, you must first identify the computer ID or target ID of the computer on which the DSLS license key will be installed. (Computer ID is the technical term used in product manuals; Target ID is a generic term used in the License Key Request order process.) To identify your computer ID:

(0) Optionally, view this video which illustrates the process:
https://www.3ds.com/assets/Terms/SoftwareKeys/DSLStarget/DSLStarget-LD.mp4

(1) Download and extract the contents of the following ZIP file to the computer on which you will install the DSLS license key: 
https://www.3ds.com/assets/Terms/SoftwareKeys/DSLicTarget125.zip

(2) Run this command to identify the Computer ID: DSLicTarget.exe –t

(3) Use the Computer ID to complete your license key request.
Use the Install from scratch option during (pre)installation of DSLS only in case you have unresolved installation issues and want to do a kind of reset. Otherwise use default installation options.
In case of Install from scratch please contact us as you will need new license keys for your products which we have to order from Dassault Systemes - they take some time to issue.
How to Install CATIA V5
1. Go to: 3ds.com/support/download/
2. Select "Access Your Download."
3. Log in using your Dassault credentials.
4. Select V5.
5. Select the appropriate Release year and select Golden from the Level drop-down menu
6. Find the required edition of CATIA (PLM Express, P3, P2, or P1).
Haikad Infotech does not recommend the suspension of license fees for the CATIA product, although the user company has the right to make such a decision. Suspension of these fees no longer permits receipt of regular updates to the CATIA software. This results in an inability to operate in the automotive supply chain due to incompatibility of file formats of each higher version of the product to the previous one.

It is important to know the regular update to a higher version in automotive OEMs takes place annually or every two years. CATIA version upgrades at automotive OEMs are coordinated globally and followed by automatic version change at all major automotive OEM vendors. We recommend that before a decision is made to suspend license fees, this is coordinated with the central IT department of the respective user company as well as with the major supplier companies.

If the decision is made to suspend license fees and the CATIA product needs to be updated, this will result in the payment of annual fees for all years in which the product was not maintained or re-purchased. Most often this is financially unprofitable.
If you have licenses with an expiration of 5 years, you should have licenses in TOS (termination of support). If the problem is happening now the possible causes could be more than one:

1- You have a problem with the license server. It is possible it is not working or some similar problem.
2- You have installed a new version of CATIA, but since their licenses are TOS, CATIA will not work. You need to use the highest version of CATIA V5-6R2022 or 2021
3- There is a time difference between the license server and the client, if this difference is greater than 2 hours, CATIA will not work.

Dassault Systèmes разрешава VPN достъп, ако:
- използвате фирмена мрежа;
- използвате лиценз в рамките на същия юридически регион (напр. Европа).
Но не разрешава:
- системата да бъде постоянно използвана в държава извън региона на закупения лиценз (пример: лиценз купен в ЕС, а ползване в Азия за дълъг период).

Временно използване за работа от разстояние обикновено е приемливо.
Generating a single license that can be used for both Wi-Fi and docking station operation in CATIA is not possible due to Dassault's licensing policies. However, we do offer two alternative solutions to address your needs:

Solution 1: Server License With a server license, all the necessary licenses would be hosted on a server machine. When your employees use a docking station, their laptops will connect to the license server, allowing CATIA to function. When they leave the office, they can temporarily check out a license as an offline license, with a maximum duration of 30 days. If needed, this offline license duration can be customized to 1 or 2 days, depending on your specific requirements. When your employees return to the office, they can return the license to the license server. If a user checks out a license for a specific period, for instance, 2 days, and does not return to the office during this time, the license will automatically deactivate on their laptop and become active on the license server.

Solution 2: Nodelock License With a nodelock license, we can tie the license to the Ethernet card of each individual laptop. Your employees can disable the docking station's network card when it's not in use and connect their laptop's Ethernet card to your network. CATIA will operate seamlessly with this configuration. It's important to note that your employees would need to make a one-time setting adjustment on their laptops. By default, laptops may disable the network card to conserve power when not connected to Ethernet. This setting should be configured to ensure the network card remains active at all times.

Both of these solutions aim to provide the flexibility and convenience you require while still utilizing your existing licensing setup. If you have further questions or need assistance with the implementation of either solution, please don't hesitate to reach out to us.
There are two solutions to this problem:

1. Network License: You can obtain a network license generated from one of your servers. When using the docking station, you'll access the license server. Before disconnecting your laptop from the docking station, you can take an offline network license for a set period (e.g., one or two days). This ensures uninterrupted access to CATIA in both scenarios.

2. Network Card Configuration: If possible, you can disable the network card on the docking station and configure your system to use your laptop's network card. This way, you can generate the license based on your laptop's network card, resolving the issue.
The issue arises due to the use of different network cards when working locally and with a docking station. The docking station typically has its network card, causing CATIA to generate licenses based on that card when in use. When working locally, your laptop uses its network card with a different target ID, causing CATIA to not run in this scenario.

More often than not, CATIA V5 users save their models in the correct release. The release number is often defined after the version number, for example CATIA version 5, release number 20 would be known as CATIA V5R20.

SAVE AND RELEASE

It is important that users working in collaboration with customers, suppliers, and other users ensure that all models are saved in the same version and release of CATIA.
CATIA is only backwards compatible, meaning that if the user saves a file in CATIA V5R20, they would no longer be able to open the models in an earlier release such as CATIA V5R18. The naming format changes with later releases of CATIA V5 which are compatible with ENOVIA V6. These release numbers are defined in a format whereby the year of release is identified; e.g. CATIA V5-6R2015. In this example, the version of CATIA is still V5 and the release can be ‘nicknamed’ R25.

WHAT HAPPENS IF YOU TRY TO OPEN A CATIA V5 FILE IN A LOWER RELEASE

The image below shows a typical error message obtained when a user tries to open a CATIA V5 file in a lower release than it was last saved in:

 

 

In order to determine which release of CATIA V5 was last saved in.......

 


Find the .CATPart file (smaller in size the better) and open it in a notepad:



Ensuring the mouse cursor is at the top line, perform a find (CRTL+F) and search for string “save”:



Upon pressing “Find Next”, find the line which states your release:



In the above example, this particular CATIA V5. CATPart file was last saved in CATIA V5-6R2018 (CATIA V5R28), thus can only be opened on this release or higher.

Most of the companies have recognized that modules MCE, FPE, KAE and HDX contribute the most to ease of everyday use of CATIA, and by using these modules engineers can best respond to the challenges they face in the design process. MCE module enables advanced functions within the Part Design and Assembly Design interface, FPE module is used to work with sheetmetal and with welds, while KAE module allows parametric design.
Софтуерният лиценз е юридически обект, койтоо дава възможност на потребителя да използва и / или разпространява определен софтуер. По-голямата част от софтуерните лицензи са под формата на поредица от букви, цифри или и двете, обикновено уникални за конкретен потребител или група потребители. Някои програми могат да се лицензират и чрез лицензен файл за определени операционни системи.
Софтуерът на Dassault Systmes се лицензира чрез лицензен файл. Самият файл управлява колко потребители имат право да използват софтуера и / или какви функции на софтуера са налични. В TECHNIA по-голямата част от нашите клиенти ще получат лиценз за конзола за управление на потребителски лицензи на IBM (LUM), конзола за Dassault Systmes License Server (DSLS) и конзола за управление на Flex License Management.
1. Ensure a Dassault Systmes product is installed (e.g CATIA V5)

2. Browse to C:ProgramDataDassaultSystemesLicenses

NOTE: If the “Licenses” folder does not exist, browse to C:ProgramDataDassaultSystemes and create a NEW FOLDER called “Licenses”.

3. Inside the Licenses folder, open DSLicSrv.txt
NOTE: If the “DSLicSrv.txt” text file does not exist, create a TEXT DOCUMENT called “DSLicSrv”.

4. In the text file “DSLicSrv”, enter the required information in the following format::

NOTE: The ServerName should be entered exactly as it is named. The licensing port by default is 4085, please use 4085 (Unless this was changed during installation). E.g. If the License server is called “server_1” the text file should have a line “server_1:4085”. If there is an additional server, e.g. server_2, simply enter it in the next line.

5. Save the text file and proceed to open your DS Application

Troubleshooting
Can’t connect to the license server? Check the following…

A. Is Window’s firewall off on both the client and server?
B. Can you ping the server?
C. Have you got the latest DSLS?
D. Is the spelling of the server name and/or port number correct?
Please copy the licences received onto the computer.

Инсталация на лицензния сървър на Dassault Systemes DSLS не е възможна на виртуална машина. Това е описано и в техническите харектеристики на DSLS сървъра. Тези ограничения имат техническо, но и юридическо естество и са свързани с ограничаване на нерегламентираното и непроследимото ползване на продуктите на Dassault Systemes.
