Parallelization via MPI not working

[matthiasneuner]

Hello,
running a job using parallelization via MPI causes following error:

singularity exec abaqus-2017-centos-7.simg abaqus j=abaqus_test2017 cpus=8 interactive

results in

Host system is an up-to-date Manjaro distribution

Note that this issue occurs for real MPI jobs only, for instance if the iterative solver is chosen by solver=iterative in the *step keyword.
Using parallelization via threads as it is default for the direct solver caues no error and works as intended, so to reproduce the error the iterative solver may be chosen.

MPI parallelization is working for me with the 2018 setup from this fork https://github.com/jomority/abaqus-2018-centos-7-singularity on Ubuntu 16.04 LTS Server host. Have you made sure you did try with the abaqus_v6.env file provided by the installation? I had a custom one in my execution directory that shadowed it and caused simulations using MPI to fail (Abaqus Error: MPI launcher '' not found. in my case).
