Nonlinear transient analysis does not support nonlinear contact analysis?

gslee

Hi,

My load step is nonlinear transient and my model contained the contact.

Output message is as follows.

My model does not have a linear analysis SUBCASE.

'the gap/contact behavior depends on the initial open/closed status and does not change.'

-> It means contact status is not updated.

But the status is updated for each iteration in my results.

Why does the message appear? is it just only information?

Thanks.

Could you share .out file of the run?

gslee

Hi,

I send the output file in the dropbox.

Thanks.

Rahul Rajan_21763

Shared out file also contains 3 warnings. How many loadstep you have & any specific reason for having FREQ1,DISP & ACCEL output?

gslee

I have only one loadstep.

FREQ1 is just remaining load collector.

The reason about DISP&ACCEL ouput is to see if DISP & ACCEL output comes in .pch files and see them in HyperGraph.

But .pch files is not opened in HyperView.

Since the analysis is converged successfully you can ignore information 2406.To post process displacement and acceleration in Hyperview request output in op2 or H3d format.

Thank you very much.

I have one more question.

What is the purpose of .pch file?
