MPIRUN

[Li-Ben512]

Hello，everyone.

I have successfully compiled CDFEM (OpenFoam 5.x, Liggghts 3.8), but there are still a problem when running multiphase case, eg dambreak. I try to modify openmpi, etc., but no effect. Any help? Thank you.

mpirun was unable to find the specified executable file, and therefore
did not launch the job.  This error was first reported for process
rank 0; it may have occurred for other processes as well.

NOTE: A common cause for this error is misspelling a mpirun command
      line parameter option (remember that mpirun interprets the first
      unrecognized command line token as the executable).

CFDEMcoupling-PFM only works correctly in combination with LIGGGHTS-PFM, not Liggghts 3.8.

Hello Danicl

Thank you for your help. The above is a writing error , and I am using LIGGGHTS_PFM from github. The environment variables setting were abided by manual. I am going to reinstall it.

The cfdemmultiphase case could run after reinstalling, but only in the the terminal that compiling CFDEMcoupling. If closing and opening anohter terminal, the error will occur again.

You mostly likely did not add the sourcing of the CFDEMcoupling bashrc file to your global .bashrc file. If you don't want to execute source ~/CFDEM/CFDEMcoupling/etc/bashrc each time you open a new terminal, you need to add a corresponding line to your global .bashrc file (like it's describe for OpenFOAM in the manual)

Thank you very much for your help. The problem is by the environment variables, and I have successfully ran the code. Thanks again!
