Specifies a value for the weight of the rigid element. The rigid material weight is the weight of the rigid excluding insulation, refractory, cladding, or fluid. If left blank, then the weight of the rigid defaults to 0. A rigid element with zero weight is often used as a construction element, used to move a centerline load to the shell wall, or used to model the effective stiffness and thermal growth of a piece of equipment.
If left blank or 0, then the software does not add the additional weight due either
to insulation, refractory, cladding, or fluid.
