Optistruct : Equal and opposite forces behaviour

Altair Forum User

Hello,

 

i am applying an equal and opposite force on my model (in +Z & -Z direction). I am expecting the displacement from both the sides in final result....but unfortunately the the displacement is only in +Z axis.

 

Is the solver first applying the force in +Z direction and then in -Z...... or does it apply forces simulateously in both direction?

 

I defined 2 different loadsteps for F1 & F2 (with same constraints and NLPRM card).

 

Pls help

Hi Palash,

 

 

Is there a reason to you have both +Z and -Z force in separate load collectors?

 

Try with both loads in single load collector and single load step.
