embeddings()

template<class PositionType, class ValueType>

std::size_t Dumux::PointSource< PositionType, ValueType >::embeddings ( ) const

inline

get the number of embeddings for this point source

Note

A point source might be located on the intersection between several scvs. If so, there are point sources for every neighboring scv with the same position. embeddings returns the number of neighboring scvs. Example: If I want to inject 1kg/s at a location that is on the inner face of an scv the point source exists in both scvs. Both have a value of 1kg/s. We then divide the value by the number of embeddings to not inject 2kg/s but 1kg/s.

This division is done in the problem.scvPointSources() if this behaviour is not explicitly changed by e.g. overloading this function in the problem implementation.
