Performing a static g-analysis in Hypermesh/Optistruct

Here we setup a static-g analysis in Hypermens and run it in Optistruct.

How to apply rotational acceleration

[@JackChessa]

There are two ways. If you have a know angular speed and want to model a centrifugal force you can use an RFORCE card (works in both Nastran and optistruct). If you have rotational acceleration due to a known nonequilibrium load state you can perform an inertial relief analysis PARAM, INREL, -2 (again works in both Nastran and Optistruct)
