WENO Test Cases

Test cases for individual functions (unit tests) as well as tests for the complete scheme (integration tests). All tests are managed with the software Catch2 and are compiled into one executable the different tests can then be run individually by selecting the appropiate tags. To list all available tags use:

tests.exe -t

For further information about command line arguments in Catch2 use

tests.exe -?

Included Tests

Currently these tests are available

1. geometryWENO Class

A test function for the Jacobian and the gaussQuad function is provided. Requires a 3D mesh given in 'globalFvMeshTest/case-3D'

Run with tests.exe [3D] in globalFvMeshTest/case-3D directory.

2. WENOUpwindFit

An integration test to compare the result of the WENO scheme to the linear scheme for the calculation of the divergence of a scalar field.

Run with tests.exe [2D] in the Case directory.

3. GlobalFvMesh test case

Test if the mapping of global to local cellID and reverse is correct. As this test is done in parallel it is not included in the Catch2 environment but uses FatalError statements to print out error messages

Mesh Study

To generate a small mesh study of the implemented WENO scheme the script WENOEXT/tests/Case/runMeshStudy.sh can be executed. It runs on the 2D mesh the WENOUpwindFit test case for a 50x50, 100x100, 150x150 mesh storing the results in a file. The results can be plotted with the gnuplot script provided in the same directory.
