Table of Contents

CADpass client secure connection (will be referred to as CADpass client or CADpass in this document) is a utility provided by CMC Microsystems that creates a secure connection between client PCs, workstations, and computer sessions, and the CMC-managed CNDN infrastructure.

This quick start guide is provided to help subscribers install and run Ansys Mechanical and Computational Fluid Dynamics (CFD) modules. These instructions are for a Windows 10, 64-bit operating system using CMC Microsystems’ CADpass to access shared licenses on the CMC License Management System (LMS).

Prerequisites for Installing Ansys with CMC License Management System (LMS)

Before you begin with this installation:

  • Students must register with CMC at
  • Faculty supervisors can subscribe through the CMC subscription page at
  • You must complete all required agreements for Ansys software use, which may be obtained at
  • You must have administrator rights for the workstation on which you are installing this software.
  • You must have a unique login name (LINUX or Windows) that does not contain a blank space. A username such as “charlie brown” contains a space, while usernames such as “charlie.brown” or “charlie_brown” do not contain spaces.

The following are examples of unacceptable login names because they are not unique: admin or administratorcmcmgrrootstcmgrsupersysadmuserownerstudent, guest, temp, and system.

System Requirements

The technical staff at Ansys provide the following recommendations for making the best use of their software, including the operating system, graphics card, CPU, and other hardware.

For a list of the features in this bundle, contact

Note: Not all modules are available for the supported operating systems (LINUX and Windows). Refer to the vendor’s recommendations for details.

Setting up CADpass client for Use with Ansys Mechanical/Fluids

CADpass client is a CMC Microsystems’ license access client and is used by subscribers across Canada to connect to our secure license server(s).

  1. Follow the instructions in the quick start guide to download and install CADpass client.
  2. Start CADpass client and log in using your CMC Microsystems Username and Password.
  3. When the CAD access window appears, double-click Ansys Campus Solutions Bundle.

A red checkmark appears next to the entry, as shown in Figure 1. Leave this checked while you are using the software.

Obtaining the Software

To obtain the latest Ansys software from CMC Microsystems:

  1. Navigate to the Ansys download site on the CMC Microsystems website at Ansys 2023  downloads.
  2. Choose the appropriate version for your operating system and download the installation file archive to your workstation.

Installing the Software

You need to install the following software:

  • Ansys Mechanical/Fluids Software (three *.iso images)

Before installing the Ansys software:

  1. Start CADpass client and log in using your CMC Microsystems Username and Password.
  2. Download the installer archive.
  3. Extract this archive into a separate temporary folder.

To install the Ansys software:

  1. In the temporary folder, open the Disk 1 archive and double-click setup.exe.
  2. In the window displayed, click Install Ansys Products, as shown in Figure 2.

Figure 2: Install Ansys 2023 Products Main Window

  1. In the next window, read the CLICKWRAP software license agreement.
  2. If you agree to the terms, select I agree to the terms, and click Next.

To learn more about your obligations under this agreement, contact If you do not want to continue, click Exit in the lower right-hand corner to end this installation.

  1. In the next window, select your installation directory and click Next to continue.
  2. In the next window, specify which parts of the bundle you want to install.

Note: The “Campus Solutions” bundle does not include all Ansys features listed by the installer program. Contact to find out which modules are included.

  1. Click Next when you have made your selections.
  2. If you want to configure your CAD Geometry interfaces, you may do so in the next window. For these instructions, select the checkbox No. Skip configuration. I will configure later and click Next to continue, as shown in Figure 3.

  1. If you are satisfied with the summary of the installation to be performed, click Next. If you want to make changes, click Back to return to the previous windows and alter your selections.

Depending upon the number of modules you selected and the hardware in your computer, installation could take an hour or more to complete. The ANSYS installer counts down the time left during your installation, as shown in Figure 4.

Figure 4: The Ansys Installer Counts Down the Remaining Installation Time

When the installation has been completed, the estimated remaining time drops to zero.

  1. Click Next to continue.
  2. The message Installation Complete is displayed, as shown in Figure 5. Completion of the Ansys survey is optional.

  1. Click Exit to close the installer.

Important: Do not install the Ansys License Manager software on your computer. It will block CADpass client from reaching CMC Microsystems’ license server ports. See Figure 6 for the location of this installer link.

Setting up Ansys Mechanical/Fluids License Access

  1. Navigate to Start | ANSYS 2023 Rx | and click Ansys Licensing Settings 2023 Rx.
  2. Select Run as Administrator.
  3. Under the License Servers title, select FlexNet Publisher.
  4. In the License Utility GUI, select Add Server Machine Specification.
  5. Use the license address as follows:
    • Port: 6624
    • Server1:

as shown in Figure 7.

  1. Click Save to accept these settings and close the window.

To Test Your Ansys Installation

  1. Ensure that you have CADpass client running and have the appropriate icon checked, as shown in Figure 1.
  2. Select one or more modules from your main Windows menu.

For example, Start menu | Ansys 2023 Rx | Fluent 2023 RX or SpaceClaim 2023 Rx or other, as shown in Figure 8.

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. An example of this interference is shown in Figure 9.

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 a maximum of four (4) cores without asking for 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, up to a limit of four, using any tool sourcing a feature named electronics_desktop, ansys or cfd_base.

Table 1 identifies the license allotments.

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

Ansys CAD ToolCampus Solutions? Base License Feature NameMax. No. CPU Cores for Feature
HFSS (Ansys EDT)electronics_desktop4
Mechanical and Mechanical APDLansys4
High-performance Computing (HPC)anshpc1
  • The Ansys license file leased annually by CMC Microsystems includes a high-performance computing (HPC) license feature named anshpc. There are hundreds of this feature types included in this license file.
  • Each anshpc HPC feature equals 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  – if more than four cores are specified – 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. One Ansys user may run a simulation on a maximum number of 64 cores (4 bases + 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.
