int faceNumber )
static

Check if the faceNumberth adjacent face is adjacent to inside cells.

So first of all, we check if the current cell is overlapping with the BH area. If this is not the case, we can return false immediately. Otherwise, we can move one cell left, right, up, down, front or left and check for this cell as well.

Check two adjacent octants.

Each face has to adjacent octants. We check if isCellOverlappingWithBHImpactArea() holds for both of them. Delete logic to isCellOverlappingWithBHImpactArea().

◆ reduceAdmissibleTimeStepSize()

void benchmarks::exahype2::ccz4::CCZ4SBH_FV::reduceAdmissibleTimeStepSize ( double timeStepSize)

Overwrite limiters time step size.

The FV solver calculates its admissible time step size in finishTimeStep(). So you can always overwrite it in startTimeStep(). Due to stability reasons, you should always reduce the admissible time step size but never ever increase it.
