Run-time Inputs

Run-time inputs are used to control the simulation setup such as the grid, solver settings, geometry, boundary conditions etc. These <key> = <value(s)> pairs are saved in a text file, with any file name, that is passed to the MFIX-Exa executable at run time:

./mfix my_project.inputs

Note

Traditionally, input files have been named inputs. However, it is recommended that you provide a descriptive name with an extension of .inputs such as fluid_bed.inputs

The input text file looks something like this:

# Run settings
mfix.stop_time = 10.0 # inline comment

# Solver settings
nodal_proj.verbose = 0
nodal_proj.maxiter = 1000

where comments are denoted with a #. If a value is not specified for a key, the default value will be used.

The following sections contain information addressing the input keywords and values for setting up a problem. Pay special attention to any prefixes for the keywords such as mfix, amr, geometry, nodal_proj etc.
