How to Set Up and Use Ansys

The Ansys MCP Server provides AI assistants with the ability to interface directly with Ansys simulation products including Fluent (CFD), MAPDL (structural/mechanical), and other PyAnsys-supported solvers through a unified MCP interface. It exposes tools for launching solver sessions, executing simulation commands, reading Ansys file formats, and monitoring session state, enabling engineers to drive complex engineering simulations through natural language instructions. Simulation engineers and CAE analysts use it to automate repetitive pre-processing tasks, run parametric studies, and debug simulation setups without manual GUI interaction.

Prerequisites

  • Python 3.8+ installed
  • Ansys software installed locally with a valid license
  • PyAnsys packages installed (ansys-fluent-core, ansys-mapdl-core, ansys-mechanical-core)
  • ANSYS_ROOT environment variable set to your Ansys installation directory
  • An MCP-compatible client (Claude Desktop, Claude Code)
1

Install the Ansys MCP server

Install the ansys-mcp-server package from PyPI along with the PyAnsys product packages you need.

pip install ansys-mcp-server
pip install ansys-fluent-core ansys-mapdl-core ansys-mechanical-core
2

Set the ANSYS_ROOT environment variable

Set ANSYS_ROOT to point to your Ansys installation directory. This allows the server to locate the correct solver executables.

# macOS/Linux:
export ANSYS_ROOT=/path/to/ansys/installation

# Windows:
set ANSYS_ROOT=C:\Program Files\ANSYS Inc\v242
3

Clone the repository (alternative source install)

If you prefer to install from source for development or customization, clone the repository and install in editable mode.

git clone https://github.com/knewnothing-git/ansys-mcp-server.git
cd ansys-mcp-server
pip install -r requirements.txt
pip install -e .
4

Verify the installation

Use the check_ansys_status tool via your MCP client to confirm the Ansys installation is detected and the required modules are available.

5

Configure your MCP client

Add the Ansys MCP server to your AI client configuration with the ANSYS_ROOT environment variable passed through.

Ansys Examples

Client configuration

Claude Desktop configuration for the Ansys MCP server with the ANSYS_ROOT environment variable.

{
  "mcpServers": {
    "ansys": {
      "command": "python",
      "args": ["-m", "ansys_mcp_server"],
      "env": {
        "ANSYS_ROOT": "/path/to/ansys/installation"
      }
    }
  }
}

Prompts to try

Example prompts for launching and controlling Ansys Fluent and MAPDL solver sessions.

- "Check the Ansys installation status and list available modules"
- "Launch a 3D double-precision Fluent session"
- "Read the case file at /simulations/nozzle.cas and summarize the setup"
- "Run MAPDL commands to define a steel material and create a simple beam geometry"
- "Execute APDL preprocessing: /PREP7, define element type SOLID186, create a cube and mesh it"
- "Run Fluent TUI commands to initialize the solution and run 100 iterations"

Troubleshooting Ansys

check_ansys_status reports that Ansys is not found

Confirm ANSYS_ROOT is set to the correct installation directory and is accessible in the environment where the MCP server runs. On Windows, use the full path including version number (e.g., C:\Program Files\ANSYS Inc\v242).

create_fluent_session or create_mapdl_session times out

Ansys solver startup requires a valid license server connection. Verify your ANSYS license is active and the license server is reachable. Check the ANSYSLMD_LICENSE_FILE or ansyslm.ini configuration for the correct license server address.

PyAnsys package import errors when the server starts

Install the specific PyAnsys packages you need: 'pip install ansys-fluent-core' for Fluent, 'pip install ansys-mapdl-core' for MAPDL. The server requires these packages to be installed in the same Python environment that runs the MCP server.
