Detailed Description

Point-wise refinement criterion: given the solution Q at a single degree of freedom, its position x and the time stamp t, decide whether the mesh around this point should be refined, erased (coarsened) or kept.

virtual void refineErasePointwisely(
  const double* __restrict__                   Q, // Q[{{NUMBER_OF_UNKNOWNS}}+{{NUMBER_OF_AUXILIARY_VARIABLES}}]
  const tarch::la::Vector<Dimensions, double>& x,
  double                                       t,
  ::exahype2::RefinementCommand* __restrict__  refinementCommand
);

Like all the other PDE terms, the generated method returns void and writes its outcome into an output argument. The output semantics are those of every adaptivity criterion (exahype2.api.AdaptivityCriterion).

Different to the legacy refinementCriterion(Q, x, h, t), the term is not handed the mesh size. Bounds on the mesh size are the job of the grid construction, not of the physics.

Q holds unknowns+auxiliary_variables entries.

Constructor & Destructor Documentation

◆ init()

exahype2.api.RefineErasePointwisely.RefineErasePointwisely.__init__	(		self,
		str	implementation = `None`,
		bool	stateless = `False`
	)

Parameters

implementation	str A C++ snippet that becomes refineErasePointwisely()'s body, or None (the default) to leave refineErasePointwisely() pure virtual for you to implement by hand. The empty string is a valid body: it leaves *refinementCommand untouched, i.e. at Keep.
stateless	bool Generate a static, GPU-offloadable method instead of a virtual one. Requires an implementation.

Reimplemented from exahype2.api.AdaptivityCriterion.AdaptivityCriterion.
