Constraints may be applied to a part or set using the command 'PROPERTY BOUNDARY CONSTRAINT ...' and are extrapolated out to the nodes by the interface. Where more than one set of constraints have been applied to a node they are summed at each node prior to output to the BERSAFE deck. Nodal constraints are expressed on type 72 cards (ie. fully constrained nodes). Each constraint card is packed with the maximum of 15 nodes where possible. The BERSAFE default load case of 1 is used for all constraints on a model. Elastic supports are not supported.
