Install the application#

Follow these steps to verify prerequisites and install the Ansys SimAI Pro application.

Prerequisites#

Before installing the SimAI Pro application, make sure that you have satisfied the following prerequisites.

Operating system	Windows 11
Random access memory (RAM)	At least 32 GB, recommended: 64 GB
GPU Memory	NVIDIA GPU with 16 GB
Disk Space	At least 10 GB free space
License Configuration	Valid Ansys license server information is required & Ansys SimAI Pro license increment for usage
Long Path	Enable long path on Windows

License Configuration (Required)#

Before installing, you must configure your Ansys license server information:

Check if License is Already Configured

Open Command Prompt or PowerShell.
Run the appropriate command:
- Command Prompt (cmd): echo %ANSYSLMD_LICENSE_FILE%
- PowerShell: echo $env:ANSYSLMD_LICENSE_FILE
If you see a value like 1055@myhost.mycompany.com or 1055@localhost, the license is already installed—skip to installation.
If you see nothing or the variable name itself, continue with the setup below.

Set License Server Environment Variable

You need to set the ANSYSLMD_LICENSE_FILE environment variable with your license server information:

Format: <port>@<hostname> Example: 1055@myhost.mycompany.com or 1055@localhost

Note

Contact your IT administrator or Ansys license administrator if you do not know your license server details. This information is required for components to function properly.
Contact your IT administrator if you do not know how to set an Environment Variable on Windows.

Quick Installation (Recommended)#

Right-click on install.bat and select “Run as administrator.”
Wait for the installation to complete.
Find the application shortcut on your desktop.

Manual Installation Options#

Opening Command Prompt or PowerShell

Click the Start button or press the Windows key.
Type cmd (for Command Prompt) or powershell (for PowerShell).
Left-click on the application to open it normally.

Basic Custom Installation#

Note

Make sure you create the C:\Users\%USERNAME%\SimAI directory before running the installer and you have read and write permissions to this directory.

Command Prompt (cmd):

mkdir "C:\Users\%USERNAME%\SimAI" 2>nul

cd "path\to\the\installer\folder"

install.bat -i "C:\Users\%USERNAME%\SimAI"

PowerShell:

New-Item -ItemType Directory -Path "C:\Users\$env:USERNAME\SimAI" -ErrorAction SilentlyContinue

cd "path\to\the\installer\folder"

.\install.bat -i "C:\Users\$env:USERNAME\SimAI"

Those commands install the application in your user directory and skips desktop shortcut creation.
