Running the MFIX-Exa Test Suite
MFIX-Exa comes with several tests aimed at evaluating software
functionalities. The source files as well as the required input files
for each test are located in the tests
directory. The tests
directory is copied to the build directory during MFIX-Exa configuration
process. When a test is run (see below), output files are stored in
build_dir/tests/test-name
.
There are various dependencies for comparing test results.
o To compare results to archived flow slices stored in AUTOTEST
directories with the case files, the environment variable FEXTRACT
must point to the location of the AMReX fextract
utility located in
the directory, amrex/Tools/PostProcessing/F_Src
. Additionally,
numdiff
must be installed for comparing results.
o To compare point-by-point field data, the environment variable
FCOMPARE
must point the AMReX utility plt_compare_diff_grids
found in the directory, amrex/Tools/PostProcessing/F_Src
.
Additionally, the environment variable MFIX_BENCHMARKS_HOME
must
point to the location of a local regression test data set. See
Generating local regression test data for instructions on creating a
local regression test data set.
Run all tests
> cd to mfix-build-dir
> ctest
List all tests (without running them)
> cd to mfix-build-dir
> ctest -N
Run a particular test by the index listed in ctest -N
> cd to mfix-build-dir
> ctest -I 3,3 # run the third test
Run a particular test by name
> cd to mfix-build-dir
> ctest -R DEM01 # running all tests with "DEM01" in the test name
Run a particular test via make
> cd to mfix-build-dir
> make run_DEM01-x # running "DEM01-x" and output to the screen
Run specific
If the environment variable GRID is defined, it specifies which grid types to run for the test(s). If GRID variable is not defined, the default is to run the tests for all grid types. > env GRID=”tiled” ctest -R DEM01 # running all tests with “DEM01” for tiled grid > env GRID=”single multiple” ctest -R DEM01 # running all tests with “DEM01” for single grid and multiple grid > ctest -R DEM01 # running all tests with “DEM01” for all grid types (single, multiple, tiled)
Run a user-defined case
> ./mfix inputs-myrun
inputs-myrun is a text file containing the AMReX input parameters; this can be named anything as long as it is the first argument following the executable. Note that many of the problem parameters are still defined in mfix.dat.
