Running a Simulation

From the Analysis section of the Flow analysis assistant panel, select Run flow optimization.

Choose the Location where the optimization (simulation) is run:

Option	Description
Local interactive	Runs the simulation on your computer (the local host) and enables you to monitor the simulation actively.
Local noninteractive	Runs in the background on your computer. While the simulation is running, you can continue working in your current session. Running simulations in the background is useful for larger models or simulations that take a long time to complete. The simulation is locked while it is running. You can review the simulation in the app, but you cannot modify any features. You can close the app or your session while the simulation is running. However, your machine must remain powered on and connected to the network until the simulation is complete.
Cloud	Runs the simulation on a Dassault Systèmes cloud server if your company has purchased cloud roles and licensing. Licensing credits are always consumed when using a cloud server to cover the cloud infrastructure cost. When your session is connected to a 3DEXPERIENCE platform server on the cloud, you can monitor its progress, similar to a local interactive simulation. However, you can also continue to work on other simulation objects, similar to a local noninteractive simulation.
Remote	Runs the simulation through 3DOrchestrate if your system administrator has configured this infrastructure in your on-premises 3DEXPERIENCE platform. Click to choose 3DOrchestrate execution options such as where your simulation is run.

Select the license type.

Option

Description

Embedded

Runs the simulation on on-premises computers provided by your company, with a separate licensing mechanism that does not require any additional tokens.

While an embedded license simulation is running, additional concurrent simulations can be run using token licensing.

Credits

Runs the simulation using one-time consumable licensing credits.

Using credits is more efficient for peak computing workloads when larger, more complex simulations are being run occasionally. The number of credits consumed depends on the complexity of the simulation model, the step types, and the Performance value you specify. When a credit is consumed, it is deducted from the total count available.

Credit licensing is available only when you are connected to a Dassault Systèmes cloud server.

Tokens

Runs the simulation using licensing tokens. Tokens are suitable for sustained simulation workloads over the license term.

In the token licensing scheme, your company has purchased a certain number of simulation tokens, which are available from a pool. When you run a simulation, a particular number of tokens are checked out from the pool. The number of tokens required depends on the complexity of the simulation model, the step types, the performance value you specify, and the estimated number of cores. When the simulation completes, the tokens are returned to the pool for use by other simulation jobs. If sufficient tokens are not available at any time for a new simulation, the job is placed in a queue until some tokens are available.

Select the performance level.

As you increase the requested performance, your simulation finishes faster but requires additional tokens or consumes credits at a faster rate. The 3DEXPERIENCE platform estimates the baseline number of processor cores required to execute your simulation, based on the model size and degrees of freedom.
