11. Running MFiX on Joule

This section is for MFiX users on NETL’s HPC system Joule. MFiX is installed as an environment module, so installing it yourself is not necessary. MFiX comes with prebuilt solvers for both DMP and SMP so building a custom solver is not needed unless you have modified Fortran code. The MFiX module depends on the gnu and openmpi modules, so when you load the MFiX module via module load mfix you will automatically get the correct versions of these dependencies (currently, gnu/13.2.0 and openmpi/4.1.5/gnu/13.2.0.

11.1. Running the GUI

1. Load the MFiX 24.2 module:

   $ module load mfix/24.2.3
   

2. Run the GUI:

   $ vglrun mfix
   

3. To build from the GUI, see: Building Custom Interactive Solver.

4. To build from the command line, run:

   $ build_mfixsolver
