Hi everyone,

I ran into a problem to construct ALE model, hope someone can help me to figure it out.

Please see first figure, that's an original model. Use a rigid body to compress an object then some elements will distort severely. After some increments the analysis break down due to error message about excessively distorted element.

Then I try to build ALE model to overcome excessively distorted error in previous case. See second figure, I didn't do to much to set my model. Just turn on ALE adaptive mesh option and choose the domain which I hope remesh during analysis. The error message mention "The requested number of domains cannot be created due to restrictions in domain decomposition" as third figure.

I thought there may be some problem about parallelization cause I use 8 multiple processors. So I attempt to cancel multiple processors option. Though I can submit the job successfully but it result in weird phenomenon like forth figure. Hope somebody can help me to solve the problem.

Thank you,

Adam Cheng
