Instance dissapears during analysis

[keulehans]

Hi guys,

I have a problem with analyzing in Abaqus. I want to put two already analyzed (deformed and with residual stresses) plates into one unanalyzed U-Part like the following picture.

The little yellow circles are the tie constrains between the deformed plates and the U-Part. I imported the plates as deformed parts from a previous Abaqus analysis. In this previous analysis, the plates also got residual stresses. I import those with Initial State - Predefined Fields as shown in the next picture.

At the end I give Boundary Conditions and Forces like in the next picture.

Then I analyze the whole thing and Abaqus completes the job without errors. But when I look at the results I get this:

The first plate is analyzed correctly, but the second plate just dissapears.

Does anybody know why the second plate dissapears and how to fix it?

Thanks guys!

Got it guys. When importing deformed parts and putting Predefined Fields (Initial State) on them some Node/Element Sets are not imported. Its necessary to redefine most of them after importing.
