Distributed mass

Alessia

Hello everyone,

I'm using Optistruct solver and I'd like to add 3 kg on the white surface for a static analysis and a normal modes one.

Does someone know how?
Thank you

you can use the 'Masses' command to add a concentrated mass and apply it to a RBE3 element connected to all nodes of this face.

Or you could use NonStructuralMass (NSM) and add a mass/area to your shells.

• Do I need to add these masses to the loadsteps (just like we do with constraints or loads)?
• Do I need to add a Load Collector "GRAV"?
