Question Regarding Overlapping Blocks in Analysis

julia4567

I have completed the analysis, but the ends of the blocks are overlapping with each other.
Can I trust the results under these conditions?
I would appreciate any advice on what adjustments I should make.
I am attaching the OUT file and model file for your reference.
Thank you.

Hi Julia4567

First of all I would suggest to run the analysis on a quarter model only with symmetric boundary conditions. This should save you much time for debugging and analysis.

Regarding your question:
The answer is depending on what you are interested in.
The overall behavior seems correct although the contact fails in the edges.
In case you are especially interested in the stresses/displacements at the edges, these results are definitely wrong.

Maybe the following options should be considered:
-Swapping Main/Secondary definition in the contact
-Use N2S Contact definition
-Do not use LGDISP and CONSLI
-Use of friction for non-freezed contacts

Best regards
