Troubleshooting Your Installation

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

  • Anti-virus Programs
    Some anti-virus programs may interfere with the Ansys installer. If you find that you cannot complete this installation, shut off your anti-virus programs temporarily and try again. Figure 5 displays this error message.

Figure 5: Machine Configuration Failed Error Message

  • Firewall Programs
    Firewall programs may block Ansys software access to the Internet. This will prevent you from using the online tutorial and help file features.

    Make sure that you give permission for the software to communicate with the Ansys website by selecting the appropriate check box as shown in Figure 6.

  • Windows Update Issue
    A problem has occurred for Ansys EDT users that have applied Windows 10 update KB4571756 (~ September 2020). This problem is identified in the following link:

    This problem happens during installation, though may also occur when trying to run Ansys from the Start Menu. The error code reported during installation is 3221227010.

    The solution is to create an environment variable that turns off the driver causing this error.

    To do this, follow these steps:

    1. Use the Windows search and enter system environment.
    2. Click on the selection Edit the system environment variables to open the System Properties.
    3. Go to the tab Advanced.
    4. Click on Environment Variables… at the bottom of this pop-up.
    5. In the window System Variables, click on New…
    6. Create the following variable:


Figure 7 shows how to edit the user variable.

Variable Value: 1

If you have followed these instructions and cannot start EDT, open a support case with CMC Microsystems’ technical staff for assistance.

Other Tricks and Tips

To make use of the high-performance computing (HPC) feature in Electronics Desktop, you must set this license feature to Pool on the HPC and Analysis Options screen.

To set the license feature, do the following:

  1. Go to the Electronics Desktop menu.
  2. Select Tools | Options | HPC and Analysis Options…
  3. Select the tab marked Options and locate the menu called HPC License.
  4. Click the pull-down arrow in the HPC License field and change it to Pool as shown in Figure 8.

Figure 8: HPC License Feature Selection Screen

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., HFSS, Maxwell, or SIwave) 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 its cores for computations.

Table 1 identifies the license requirements.

Table 1: Main Modules Versus Max. No. CPU Cores

Ansys CAD ToolCampus Solutions’ Base License
Feature Name
Max. No. CPU Cores for Feature
HFSS (Ansys EDT)electronics_desktop4
Mechanical and Mechanical APDLansys4
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 this feature type included in this license file.
  • Each anshpc HPC feature is equal to one (1) additional physical core you may use. When a simulation is started, an Ansys module (e.g., Fluent or HFSS) checks out anshpc features to fill the user’s 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 on the anshpc feature of 60. This means that one Ansys user may run a simulation on a maximum number of 64 cores (4 base + 60 HPC).

Note: If you find that you are experiencing denials when attempting simulations, your token(s) may be in use by another member of your 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.
