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.

This quick start guide is provided to help subscribers install and run Ansys Electronics Desktop (EDT) CAD modules. These instructions have been tested on Windows 10, a 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, you must do the following:

  • Students must register with CMC at
  • Faculty supervisors can subscribe through the CMC subscription page at
  • Complete all required agreements for Ansys software use, which may be obtained at
  • You must have administrator rights for the computer 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 administrator, cmcmgr, root, stcmgr, super, sysadmin, user, owner, student, 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.

Setting up CADpass Client for Use with Ansys EDT

The CADpass client is a CMC Microsystems license access client 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 the CADpass client.
  2. Start the CADpass client and log in using your CMC Microsystems Username and Password.
  3. When the CAD access window appears, double-click Ansys for Academics.

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

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 cannot complete this installation, temporarily shut off your anti-virus programs and try again.

Firewall Programs

Firewall programs may block Ansys software access to the Internet. It will prevent you from using the online tutorial and help file features. If you suspect that your firewall may be blocking your CADpass client license access, check your firewall rules.

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

For high-performance computing (HPC) applications, Ansys for Academics 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 asking for 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, up to the limit of four, using any tool sourcing a feature named electronics_desktop, ansys or cfd_base.

Table 1 identifies the license allotments.

HFSS (Ansys EDT)electronics_desktop4
High-performance Computing (HPC)anshpc1
  • The Ansys license file released annually by CMC Microsystems includes a high-performance computing (HPC) license feature named anshpc. There are dozens 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.
  • This way, our subscribers share one large pool of licenses across our research community.

To Enable the Use of the anshpc Feature

  1. Go to the Ansys EDT menu

Tools | Options | HPC and Analysis Options

  1. Select the tab Options.
  2. Set the HPC License menu to Pool, as shown in Figure 5.

Note: If you are experiencing denials when attempting simulations, your token(s) may be used 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.
