title: How do I solve this path error when trying to run ANSYS with parallel processing using MPI?
body: <p>I am currently attempting to write a batch file that will open ANSYS Autodyn using MPI on a virtual machine. Whenever I attempt to start the program however, I get the following message;</p>
  
  <blockquote>
    <p>WARNING: No cached password or password provided.
             use '-pass' or '-cache' to provide password</p>

    <p>--- Error detected in: module: OMopen_file ---

    Inc\v162\aisol\AUTODYN;.
    MPI Application rank 0 exited before MPI_Init() with status -1</p>
  </blockquote>
  
  <p>The problem is caused by the fact that the path specified in the last paragraph there should be;</p>
  
  <blockquote>
    <p>C:\Program Files\ANSYS Inc\v162\aisol\AUTODYN\winx64</p>
  </blockquote>
  
  <p>The problem is that I cannot find the variable that specifies that path, and so I cannot change it. Does anyone know how to solve this problem? Or am I stuck using just one core for the time being?</p>
  
  <p>The batch file code is;</p>
  
  <pre><code>set MPI_ROOT=C:\Program Files\ANSYS Inc\v162\commonfiles\MPI\Platform\9.1.2.1\winx64
  "%MPI_ROOT%\bin\mpirun.exe" -mpi64 -prot -e MPI_WORKDIR="C:\Users\umjonesa\AppData\Roaming\Ansys\v162\AUTODYN" -f applfile.txt
  PAUSE
  </code></pre>
  
  <p>That opens the .txt called applfile;</p>
  
  <blockquote>
    <p>-e MPI_FLAGS=y0 -h localhost -np 1 "C:\Program Files\ANSYS Inc\v162\aisol\AUTODYN\winx64\autodyn.exe"
    -h localhost -np 3 "C:\Program Files\ANSYS Inc\v162\aisol\AUTODYN\winx64\adslave.exe"</p>
  </blockquote>
  
  <p>which should open an autodyn window with one master and three slaves.</p>
