SMS:RMA4 BC Elements

A boundary mass loading can be added to an element in the mesh by selecting first the desired element and then the RMA4 | Assign BC menu command. This opens the RMA4 Assign Element Mass Loading dialog where a constant or transient entry can be made in grams/second for each constituent defined in the RMA4 model control dialog. The time variant option uses a XY Series File, XYS Format editor to enter a series of time step-mass loading pairs. The time steps should be consistent with those of the RMA4 simulation and for each constituent. The mass loadings may be deleted using the RMA4/Delete BC menu command.
