!> @brief Calculates IP volume.
|
||||
!> @details The IP volume is calculated differently depending on the cell type.
|
||||
!> 2D cells assume an element depth of one in order to calculate the volume.
|
||||
!> For the hexahedral cell we subdivide the cell into subvolumes of pyramidal
|
||||
!> shape with a cell face as basis and the central ip at the tip. This subvolume is
|
||||
!> calculated as an average of four tetrahedals with three corners on the cell face
|
||||
!> and one corner at the central ip.
