local csys

LRIGA

Hi at all,

there is a way to reference a load (force or gravity ) to a local coordinate system?
clearly is possible to decompose force direction to another system using a simple rotation matrix but sometimes
is useful apply forces to local system directly

Thanks

Sergio

You must use the CCX solver, then define a local coordinate system using CCX Custom Model Definition and *TRANSFORM card relative to a node set, then the loads applied on that node set in the GUI will be related to this new CS

Thanks Sergio,
I've search for that calculix keyword as you suggest (https://web.mit.edu/calculix_v2.7/CalculiX/ccx_2.7/doc/ccx/node253.html)
I've attached a simple example for someone who have the same question, red arrow for initial applied force and green the trasformed one
