# Global Block

The Global block contains settings for coupling the X, Y, and Z direction force computations and the X, Y, Z direction moment computations. This block is mandatory.

Parameter Type Units Description
EPSILON Real No-units Unused at present. Ignore when reading file.
COUPLING String No-units Valid choices are:
UNCOUPLED ->
X, Y, and Z forces computed independently.
CYLINDRICAL ->
X and Y forces are coupled.
SPHERICAL ->
X, Y, and Z forces are coupled.

The following is an example of a Global block:
