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, there are three directional variations; these are identified in the repository as, for example, FLD01-x, FLD01-y, and FLD01-z.

For each direction, where appropriate, 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
