Doesn't Abaqus do its own environment setup? I.e., I'm *guessing* that you should be able to set your environment startup files (e.g., $HOME/.bashrc) to point your PATH / LD_LIBRARY_PATH to point to whichever MPI implementation you want, and Abaqus will do whatever it needs to a) be independent of your environment, and b) be able to function with whatever underlying MPI it wants to use.
This is a supposition on my part -- I am not an Abaqus user. Note, too that popular MPI implementations support a command line option such that if you invoke the absolute path name of mpirun/mpiexec, it'll setup the PATH / LD_LIBRARY_PATH on the remote servers to echo that of the local server.
