Continuous Integration
======================

The following regression tests are run every time a commit is pushed to the main
MFiX-Exa repository on the NETL gitlab.

For each of the tests in the chart below, we have identified the "-x" version
in the table, but each of the tests also has a "-y" version and a "-z" version.

Similarly -- for many of these tests there are multiple versions,
with the following notations:

  * SGS: single grid serial

  * MGS: multiple grid serial

  * TGS: tiled grid serial

  * MGP: multiple grid parallel

Below Ng = number of grids, Npa = number of particles, Np = number of MPI ranks.

All the FLD cases are fluid-only.
All the DEM cases are particle-only except for DEM06 and DEM07 which are fluid and particles;
these both use the "BVK2" drag type.
In all cases the particle data were read in from "particle_input.dat"

None of these tests have non-rectangular geometry.

"NSW" means "No Slip Wall" and "Per" is "periodic."
"MI/PO" refers to Mass     Inflow at the low end of the domain and Pressure Outflow at the high end.
"PI/PO" refers to Pressure Inflow at the low end of the domain and Pressure Outflow at the high end.

Additional detail about these problems is given in tests/README.md
