Member Function Documentation

run()

virtual void peano4::grid::tests::GridTraversalEventGeneratorTest::run ( )

overridevirtual

This routine is triggered by the TestCaseCollection.

Implements tarch::tests::TestCase.

testAreFacesLocal1()

void peano4::grid::tests::GridTraversalEventGeneratorTest::testAreFacesLocal1 ( )

private

testAreFacesLocal2()

void peano4::grid::tests::GridTraversalEventGeneratorTest::testAreFacesLocal2 ( )

private

A simple setup that I extracted from a bug in the code:

In this example, the middle cell of the 3x3 coarsest pattern is deployed to rank 1. On rank 1, the marked face thus should not be local on rank 0.

testCreateEnterCellTraversalEvent1()

void peano4::grid::tests::GridTraversalEventGeneratorTest::testCreateEnterCellTraversalEvent1 ( )

private

   Test to find out where faces go to and come from

   We run through this cell from left bottom to top right and this cell is
   created while we span this whole third level from scratch. That is, all
   grid elements are new. Indeed, only the bottom two vertices are unrefined,
   as they have been created by another cell before (the one below), while
   the top two vertices are new. The left top one has been created before
   (through the left neighbour), so the right top vertex is the one which is
   actually to be created by this event.

   The vertex indices in the output above are correct. Only one vertex (number
   three) is to be created. The flags for the faces are however wrong: The
   left and bottom one indeed are to be taken from temporary stacks, as we've
   visited their other adjacent neighbour/cell before. But the top one is to
   be created (correct) as well as the right one (wrong in dump above).
