3.4 Advanced Entity Manipulation

void FEM_Mesh_data_offset(int mesh,int entity,int attr, void *data, int first, int length, int datatype,int width, int offsetBytes,int distanceBytes,int skewBytes);
SUBROUTINE FEM_Mesh_data_offset(mesh,entity,attr,data,first,length,datatype,width, offsetBytes,distanceBytes,skewBytes)
INTEGER, INTENT(IN) :: mesh,entity,attr,first,length,datatype,width
INTEGER, INTENT(IN) :: offsetBytes,distanceBytes,skewBytes
datatype, intent(inout) :: data(width,length)

This routine is a more complicated version of FEM_Mesh_data. It allows you to get or set a mesh field directly from a user-defined structure. See the documentation of IDXL_Layout_offset in Section 8.2.2 for details on how to set offsetBytes, distanceBytes, and skewBytes.

void FEM_Mesh_data_layout(int mesh,int entity,int attr, void *data, int firstItem, int length, IDXL_Layout_t layout);
SUBROUTINE FEM_Mesh_data_layout(mesh,entity,attr,data,first,length,layout)
INTEGER, INTENT(IN) :: mesh,entity,attr,first,length,layout
INTEGER, INTENT(IN) :: layout

This routine is a more complicated version of FEM_Mesh_data. Like FEM_Mesh_data_offset, it allows you to get or set a mesh field directly from a user-defined structure; but this routine expects the structure to be described by an IDXL_Layout object.
