GetNormalsByElement()

• This method puts components of normal vectors at each node of a mesh face (at each face of a mesh volume) into the output array. Returns false if some problem was detected during calculation of normals. Id is an identifier of the mesh element. IsNodal, when true, means that normals at mesh element nodes are needed. If nodal normals are not available, or IsNodal is false, or the mesh element is a volume, then the output array contents depend on the element type: face: a normal calculated by GetNormal() is duplicated for each node of the face; volume: normals to all faces of the volume are computed (not for each node!). MaxNodes is maximal number of nodes an element can consist of. Normals contains the result.
