Units

This is the next sub-level in the tree under Analysis. It provides an option to define a unit system within the Analysis dialog.

Unit System:

The units selected within the Analysis form are defined only for that specific Analysis. The units are also exported to the Nastran Bulk Data file as PARAM, UNITS, MM.

Once the units are defined, they will show up in the tree under Analysis and in the results output text on the lower left corner of the canvas, as shown in the below image.
