I get the following error when attempting to run an example nFX file on Ubuntu via an Oracle VM.

I believe there are 2 issues... 1) file does not exist and 2) some MPI issues.

Perhaps someone can point me in the right direction? Much appreciated.

    Try this:

    • "cd" to installation folder of nanoFluidx and type the following command:
    • find . -name "liblmx*"

    Check the output if you found the missing file?

    I know nothing about nanoFluidx, maybe you have to run app via a script instead of this executable?

    Have you sourced the appropriate setup script - to establish the proper environment?  Typically in the installation directory you'll 'source' set_nFX_environment.csh or set_nFX_environment.sh - depending on the Shell you are using.  This adds items to PATH, LD_LIBRARY_PATH, etc.
