About Credits

Credits are one-time consumable licensing items that you can use to run a simulation. Using credits is more efficient for peak computing workloads when you occasionally run large, complex simulations.

In credit licensing, your company has purchased a certain number of credits that are available from a pool. When a credit is consumed, it is deducted from the total count available.

For SimUnit credits, the number of credits consumed depends primarily on the number of cores you use, with some additional factors based on the domain in which you are simulating. Some solvers can assess the complexity of your model and the features it contains to assign a compute configuration that should run your simulation most efficiently and economically. Occasionally you might want to override this configuration. You can edit the compute configuration by selecting the number of cores.

For compute credits, the number of credits consumed depends on the complexity of the simulation model, the step types, and how quickly you want the simulation to run to completion.

For more specific information about credit consumption for SimUnit credits, simulation credits, or compute credits, see https://www.3ds.com/terms/ost/.

Credit licensing is available when you are connected to a Dassault Systèmes cloud server or when your system administrator has configured SimUnit credits or compute credits on your company's on-premises DS License Server.

For many apps, you can monitor your simulation to determine how many credits are required to run your simulation, how many credits are available, and how many credits a simulation has consumed so far.
