Nodal Masses
Use this dialog to add nodal masses to structure nodes for structure dynamic analysis or for static calculations when forces are generated for body loads (body forces as well as centrifugal and angular acceleration forces) and self-weight.
Member Mass Dialog
Use this dialog to add masses to members for structure dynamic analysis or for static calculations, when forces are generated for body loads (body forces as well as centrifugal and angular acceleration forces) and self-weight.
