EXCAV,<model>,[delta]

This command will create an excavation volume model for a model that doesn't have an excavation volume. This is to be used in conjunction with the simulation modules that use the matrices built in ANSYS®. The command will use the lowest z - level grid as a to create of the model to create a homogenous mesh up to ground surface. If there are outcropping beneath ground surface that do not extend to the bottom z-level the code will not generate excavation volume for these areas. This Model will be stored in the model number given by the user. The Ground Surface must be defined properly in the model used in the generation. The delta is a factor used match slight variations in z-level used in some models for the same embeddment level.

• model – Model number to store the excavation volume
• delta - allowable distance of z-level variation on a single level (Default = 0). Delta should be entered as a positive floating point number or else the default will be used.
