How to Solve HPC Pack/Pool Licensing Error in ANSYS Electronics Desktop

Presented by: Mark from Ozen Engineering, Inc.

Introduction

In this video, I will demonstrate how to resolve an error message related to HPC license settings in the ANSYS Electronics Desktop. HPC stands for High Performance Computing, which is crucial for performing large engineering simulations.

Understanding HPC Licenses

ANSYS offers HPC licenses in various configurations to enable the use of additional CPU cores beyond the four cores included with the base solver license. These additional cores can be used to:

  • Solve a single design faster
  • Solve multiple parametric variations, frequencies, or time steps in parallel

One popular option is to purchase HPC pack licenses, where each pack multiplies the number of additional enabled cores by a factor of four:

  • The first pack enables 8 additional cores
  • The second pack enables 32 additional cores
  • The third pack enables 128 additional cores
  • And so on...

The four cores included with the base solver are added to obtain the total number of cores available in each case. This provides a scalable cost model for applying a large number of cores to a given simulation. For example, running a model on 2,000 cores instead of 100 cores only requires two additional HPC packs.

Applicable Solvers

The solvers in the Electronics Desktop, including HFSS, Maxwell, Q3D, and iSpec, can take advantage of these HPC licenses.

Example: Bandpass Filter in HFSS

For this example, I'm showing a bandpass filter modeled in HFSS. A common error message that you might see in the message manager window is that there's not enough HPC parallel licenses. This will prevent the simulation from running with the specified number of cores.

Solution

  1. Specify the number of cores in HFSS by going to the Simulation ribbon.
  2. Click on HPC Options and then the Edit button.
  3. Set the number of cores to 8, which requires one HPC pack.
  4. To solve the error, specify the use of HPC packs if that's the type of licenses you're using.
  5. Go to the Options pane and change the HPC license setting from Pool to Pack.
  6. Click OK, go back, and press Analyze All for this example model.

The model should run successfully after these steps.

Hi, this is Mark with Ozen Engineering and in this video I'll show you how to resolve an error message related to HPC license settings in the ANSYS Electronics Desktop. HPC stands for High Performance Computing, which is an important part of performing large engineering simulations.

ANSYS offers HPC licenses in several configurations that enable the use of additional CPU cores above the four cores that are included with the base solver license.

These additional cores can be used to solve a single design even faster or to solve multiple parametric variations, frequencies, or time steps in parallel. One popular option is to purchase HPC pack licenses, where each pack multiplies the number of additional enabled cores by a factor of four.

The first pack enables eight additional cores, the second pack enables 32 additional cores, the third pack enables 128 additional cores, and so on. The four cores that are included with the base solver are then added to obtain the total number of cores available in each case.

This option provides a scalable cost model for applying a very large number of cores to a given simulation. For example, running a model on 2,000 cores instead of 100 cores only requires the use of two additional HPC packs.

The solvers in the Electronics Desktop, including HFSS, Maxwell, Q3D, and iSpec, can take advantage of these HPC licenses. For this example, I'm showing a bandpass filter modeled in HFSS.

A common error message that you might see in the message manager window is "not enough HPC parallel licenses." This will prevent the simulation from running with the specified number of cores. We can specify the number of cores in the HFSS.

To solve this error, set the number of cores that the solver should use by going to the Simulation ribbon and then clicking on HPC Options, and then the Edit button. In this case, I've set the number of cores to 8, which requires one HPC pack.

To specify the use of HPC packs, if that's the type of licenses that you're using, go to the Options pane and change the HPC license setting from Pool to Pack. Click OK, and then press Analyze All for this example model. It runs successfully.
