Hello, I try to run the compas\_fea beam frame example on Rhino and I get the attached error message. The script gets stuck in the Abaqus analysis. I have linked Abaqus in my Path folder, I can open it using the cmd prompt, and it runs, but do I need to do something else? Thanks! ![compas_fea%20error](https://us1.discourse-cdn.com/flex015/uploads/compas_framework1/original/1X/d6277246fa06ba88347a9a1c89b47f7fdf3218bd.jpeg) ---

Hi Voulp, As this is the `plot_data` part, it is most likely the Abaqus analysis has worked okay, as you are now trying to plot results. It is most probably an issue with your Anaconda/CPython install and/pr `PATH` outside of Rhino (which the `rhino` module and `plot_data` function try to access), or, a `PYTHONPATH` issue for `compas_fea`. I cannot tell which without more info. Can you pop by the office so we can find out more? Then we can post the solution back here. Andrew ---

Problem was related to your group’s installation of Abaqus which appears to not have MPI installed/support for using Abaqus MPI multiprocessing. It was not a path problem as expected above. The current temp solution is to turn off multiple `cpus` with `cpus=1` in `analyse_and_extract()`, or a later better fix is for me to enable the `THREADS` multiprocessing option. This is Issue [#100](https://github.com/compas-dev/compas_fea/issues/100) on the issue tracker. ---

Another (I guess rather obvious) option is to simply to install Abaqus MPI. Installer is (atleast for me) located at: > C:\SIMULIA\Abaqus\6.14-1\installation\_info\client\_install It should be installed automatically with Abaqus according to SIMULIA… ---

I think it has something to do with your startup install scripts for Abaqus, whenever I install, I get a pop-up saying that MPI is getting installed, so something is happening automatically my end. Either way, the problem should be resolved now as I have turned on `THREADS` instead of `MPI` as the default multi-processing option, there was no speed difference for me. See the closed issue [here](https://github.com/compas-dev/compas_fea/issues/100). Therefore you can revert to turning off `cpus = 1` (hopefully).
