Grav Card- Radioss (Bulk)

Altair Forum User

Hi,

I have used the Grav card for 1G loading of the chassis.

my doubt here is:

Would the gravity load that I have assigned, be taken up by all the elements of the chassis??

As I see no provision to assign a set in the GRAV card.

Yes the grav load will be applicable to all the elements of the chassis(ie all component).

Hi,

A gravity load is valid for the entire model, as written in the helpfile: Defines the gravity vectors for use in determining gravity loading for the structural model.

This requires the definition of a density. So you can organize your model, if you need.

Mario

PS: This is valid for implicit solutions, e.g. Radioss bulk or Nastran
