Troubleshooting Your Installation

The following suggestions are based upon difficulties some of our subscribers have had when upgrading their workstations to the latest release from earlier Ansys installations.

  • Local anti-virus and firewall programs sometimes interfere with installation programs. If you think either or both may be interfering with your license connection, check your firewall rules for permissions.

If you followed these instructions and cannot start this suite, open a support case with CMC Microsystems.

Other Tricks and Tips

For high-performance computing (HPC) applications, the Ansys Campus Solutions bundle is designed to work as follows:

  • Each time one of the main modules (e.g., Fluent, CFX, or MAPDL) is started by one of our subscribers, this module can be run on four (4) CPU cores without requiring any additional license features. Specifically, if your local workstation has a multi-core processor, you may set your simulation to call on all of its cores for computations.

High-performance Computing (HPC)anshpc1
  • The Ansys license file purchased by CMC Microsystems includes a high-performance computing (HPC) license feature named anshpc. There are hundreds of these features included in the license file.
  • Each HPC feature anshpc is equal to one (1) additional core. When a simulation is started, an Ansys module (e.g. Fluent or HFSS) checks out as many anshpc features as it can to fill the user’s HPC request, and releases these features when the simulation is finished.
  • In this way, our subscribers share one large pool of licenses with each other across our research community.
  • As of January 2021, CMC licensing staff has placed a restriction of 60 on the feature anshpc. This means that one Ansys user may run a simulation on a maximum number of 64 cores (4 base + 60 HPC).

If you find that you are experiencing denials when attempting simulations, your token(s) may be in use by another member of your research group. Look at the report here to see if this is the case. If this is not the case, then contact our office for support.
