InterpolationTest()

virtualdefault

Destructor, empty.

Member Function Documentation

run()

virtual void toolbox::blockstructured::tests::InterpolationTest::run ( )

overridevirtual

This routine is triggered by the TestCaseCollection.

Implements tarch::tests::TestCase.

testCellInterpolation()

void toolbox::blockstructured::tests::InterpolationTest::testCellInterpolation ( )

private

Interpolate a coarse patch into its 3^d children.

The piecewise constant interpolation has to copy the value of the coarse volume which contains a fine volume's centre. The d-linear interpolation has to reproduce a linear field, except next to the boundary of the coarse patch, where it extrapolates constantly.

testHangingFacesForAnyOverlap()

void toolbox::blockstructured::tests::InterpolationTest::testHangingFacesForAnyOverlap ( )

private

Interpolate onto hanging faces and restrict from them for overlaps of one, two and three.

• Both interpolation schemes have to reproduce a constant coarse face on both halves of the hanging face.
• The linear interpolation has to reproduce a field which is linear along the face, except next to the ends of the face, where it extrapolates constantly.
• Restricting a constant fine face over all 3^(d-1) subfaces has to yield this constant on the fine half of the coarse face and leave the other half untouched.

testInterpolateCellDataAssociatedToVolumesIntoOverlappingCell_linear()

void toolbox::blockstructured::tests::InterpolationTest::testInterpolateCellDataAssociatedToVolumesIntoOverlappingCell_linear ( )

private

Trivial interpolation test for constant data.

testRestrictCellForBreakingDam()

void toolbox::blockstructured::tests::InterpolationTest::testRestrictCellForBreakingDam ( )

private

testRestrictHaloLayer_AoS_averaging()

void toolbox::blockstructured::tests::InterpolationTest::testRestrictHaloLayer_AoS_averaging ( )

private

   Tests this averaging

   The test results from a real test with the Euler equations and four
   unknowns per coordinate axis. The input is as follows:

parameter tarch::la::DynamicMatrix::vectorToString(fineGridFaceEulerQUpdate.value,4*2*5): (entries=40,
