Starting with Ansys release 2020 R2, HPC licenses may be used for concurrent simulation of parametric variations, allowing you to leverage standard HPC licenses instead of extra solver licenses. Each variation, after the first, requires 8 HPC increments or 1 HPC Pack increment. Similar to non-parametric simulations, each variation provides 4 included parallel cores per variation. Additional HPC parallel cores are shared across all variations, using the same HPC rules. All licenses that are consumed during a concurrent parametric simulation are held for the duration of the simulation, based on the max count of each license required for a given variation.

You can use the Ansys Parametric Licensing Calculator (https://ansys.com/parametric) to determine the number of HPC Workgroup or HPC Pack licenses required.

When Upfront License Checkout option, is enabled in Ansys Workbench (see Using Upfront License Checkouts for Design Point Updates), a different algorithm is used to calculate the number of HPC Increments that should be checked out upfront of the parametric update.

In the case where upfront license checkout is enabled, the number of HPC increments checked out at start of parametric update=(k*(max(0,((i*j) -4)))) + ((k -1)*8).

i=number of solver and preppost enabling licenses pre-selected

j=number of cores required per simultaneous task

k=number of simultaneous tasks requested
