Detailed Description

A source term that contributes only at isolated points (e.g.

a seismic point source), as opposed to VolumetricSource, which is distributed over the whole domain.

See python/exahype2/solvers/aderdg/AbstractSolverDeclarations.py's pointSource(), which additionally takes t, dt and an index n selecting which of possibly several point sources is being evaluated - dropped here the same way h/t/dt are dropped from Flux, and n returns once PDE terms are tied to real C code snippets with proper signatures:

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

Constructor & Destructor Documentation

◆ init()

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

implementation: str A C++ snippet that becomes pointSource()'s body (the empty string is a valid, generated no-op body), or None (the default) to leave pointSource() pure virtual for you to implement by hand.

Don't add this term to a solver at all if the PDE has no point source contribution.
