Member Function Documentation

◆ getFacetNormal()

virtual MbVec3d MeXVolumeCell::getFacetNormal ( size_t  facet,
const MiGeometryI meshGeometry 
) const
pure virtual

Gets the normal to the given facet of the cell.

An application does not need to override this method.

Parameters
[in]facetThe index of the facet (where 0 <= facet < getNumFacets()).
[in]meshGeometryThe geometry of the mesh. Used to retrieve the node coordinates of this cell.
Returns
a vector.

◆ getVolume()

virtual double MeXVolumeCell::getVolume ( const MiGeometryI meshGeometry) const
pure virtual

Gets the volume of the cell.

An application does not need to override this method.

Parameters
[in]meshGeometryThe geometry of the mesh. Used to retrieve the node coordinates of this cell.
