Running MFIX on fedora with batch solver with dmp

MFiX
#1

I would like to run MFIX on a linux machine that has fedora version 25. I was able to download anaconda and create the 19.1 evironment and install mfix. I then in the activated 19.1 environment did the command “build_mfixsolver -batch -dmp -j” and it said the build was successful, but when I try to run parallel with the command “mpirun -np 16 ./mfixsolver -f base_pa.mfx NODESI=2 NODESJ=4 NODESK=2” I get

usage: pymfix.py [-h] [-f FILE] [-p] [-l LOG] [-c] [-s] [-v]
pymfix.py: error: unrecognized arguments: NODESI=2 NODESJ=4 NODESK=2

If my problem is because the anaconda mfix has not been tested on fedora, do I need to compile mfix from the tarball source?

#2

The batch solver will run serial on fedora but I am not able to run parallel.

#3

I can’t tell from your original post. Did you use --batch or -batch. If you are getting pymfix errors, I’m guessing that you didn’t get the batch (non-interactive) solver.

#4

I used -batch per 5.2.1 of the user’s guide. The batch solver does run serial without the “NODES?” keywords.

#5

pymfix.py in the error message is telling me that it is not a batch solver.

#6

Do I use --batch in the build command? Why would the serial run? So the mfixsolver command starts the interactive solver?

#7

Yes. To build the batch solver, you need to use a double-dash flag, --batch. I’m guessing the confusion came in how the website rendered the font.

#8

Yes, the formatting in the user manual is wrong. We will patch it to fix the formatting.

#9

This resolved it. I am running on a fedora machine in parallel in dmp
