Export Pressure Load in Non-Linear Static Analysis

Hi,

I have ran a non-linear static analysis.

My load application is outward pressure, and I am specifying my incremental output parameter as TIME set.

Is there a way to know, or what Global Output Request Card I should select to find out which level of increamental output correspond to the level of pressure.

Let says the pressure I define is 20 psi.

Thanks,

Jerome.

Oh, i believe that what you are looking for is NLOUT.

I am not sure if i fully understand, but do yo know OLOAD?

Hi Loisf,

Thanks for helping.

I have try to export OLOAD in my model, and I see now my analysis result have the applied force (mag) and moment. Please explain to me what the countour plot means?

I am trying to figure out output interval 0.8, what is the pressure exerted on the model inner wall.

As right now, I am running non-linear static analysis with define 20psi on the model inner wall, and I have specifying to use Hashin failure criterion.

If I say the failure index pass 1 at 0.8 output interval, can we says that the model is breaking at 0.8*20psi, which is 16psi is the failure pressure for this model?

Best regards, Jerome.
