Generation of Element Group Numbers

By default each element in the model is allocated a group number by this program according to the ANSYS element type. This allows the FEMVIEW user to identify or select different ANSYS element types that were mapped to the same FEMVIEW element type. For example, the 'SOLID73' element is given the group number 73, so issuing the FEMVIEW command `LABEL MESH GROUPS 73' will label all SOLID73 elements in the current subset of the model.

However the interface also allows the user to override this by setting the FEMVIEW element group number to either the real constant reference number or the material constant reference number for each element.

These may be selected by appending either '-realid' or '-matid' respectively to the executable name. If both options are requested the -matid option is ignored.
