Detailed Description

template<int refDim>
class ug::StdLinConsistentGravityX< refDim >

Class for the computation of the enhanced version ('Frolkovic-type') of the consistent gravity.

Implementation of the enhanced ('Frolkovic-type') version of the consistent gravity for simplices (triangles and tetrahedra) in the case of the gravity force parallel to the z-axis. For all other elements and other gravities, the same method as in StdLinConsistentGravity is used.
