License

ANSYS Electromagnetics is a suite of commercial programs, that require a license. NSC does not provide any ANSYS Electromagnetics licenses. You have to provide correct license information by yourself. Typically, the license server is run by the IT department of your university, e.g. at Chalmers, Uppsala University etc. See sections below for how to connect to a license server.

Installations on NSC Systems

Tetralith and Sigma

ANSYS Electromagnetism is available via the module system on Tetralith and Sigma. For more information about available versions, please see the Tetralith and Sigma Software list

How to run

Load the ANSYS Electromagnetics module corresponding to the version you want to use, e.g

module load ansys-em/2020R1-nsc1

This gives you access to the ANSYS Electromagnetics software.

Connect to a license server

To connect to the license server, ANSYS Electromagnetics needs the environmental variable ANSYSLMD_LICENSE_FILE. For example

    export ANSYSLMD_LICENSE_FILE=port@servername

port is a four digit number, and servername is the IP-address of the license server.

If the variable ANSYSLMD_LICENSE_FILE cannot be provided, there is a second option:

1. Create a file, that contains the following information, e.g. $HOME/license.ansys:

   SERVER <servername> ANY <FlexNet_port>
   VENDOR ansyslmd
   USE_SERVER
   INCREMENT any ansyslmd any

2. Set ANSYSLMD_LICENSE_FILE to point to the license file

   export ANSYSLMD_LICENSE_FILE=$HOME/license.ansys

The servername and FlexNet_port are provided by the IT department that runs the license server.
