  Hello Support,
  
  I am using Ansys 2025 R2 on a Linux system. The model meshes successfully, but when I start the solution, Mechanical displays:
  
  "An error occurred while starting the solver module."
  
  The terminal reports:
  
  ansys.e: error while loading shared libraries:
  
  libXm.so.4: cannot open shared object file:
  
  No such file or directory
  
  I have already attempted a reinstallation of Ansys, but the issue remains.

  This issue occurs because the Motif runtime library (libXm.so.4), which is required by Ansys, is missing from the Ubuntu system.
  
  Please install the libmotif-dev package using the following command:
  
  sudo apt-get update
  
  sudo apt-get install libmotif-dev
  
  Once the installation is complete, launch Ansys again and rerun the analysis. The solver module should start normally if the required library has been installed successfully.
