WELD

The WELD command will combine nodes that occupy the same location. The command does this by searching the node list for node that occupy the same location to create a substitution table. Then the SASSI User Interface will use the table to change the node connections of the elements. This command was designed to work with excavation only and structure only models before using MERGESOIL.

Notes: The node that have been substituted will still be in the Node list but they will not be attached to any elements. The WELD command does not change the mass, boundary condition, or interaction status of any node. The user my need to readjust these parameters before simulation. This command will change the element connections on all coincident nodes even in intended situations such as models with structural and excavation elements, or models that have springs applied by the FIXROT command.
