 I am working on composite analysis using optistruct solver. While solving I got error "program stopped due to element quality check." what should be the solution for this. whether I have to remesh again or is there any command by which element quality criterion gets automatically satisfied.

   Thanks.

Hi Bhushan,

 

You can Bypass the element quality check. Use the control card CHECKEL>>NO

 

Goto Analysis>> Control Cards>>PARAM>>CHECKEL>>NO

No, if you are using Analysis, optimization will be skipped.

 

Can you share the model file?

Bhushan,

 

OK. Since the problem is only with 2 elements, try to delete those elements and recreate again.

 

After recreating check if the problem is solved,

I'm using optimization and it didn't skipped. How to skip this iteration and continue when occurs error "program stopped due to element quality check."?

Hi @wangs8811

 

What type of optimization is it?

 

Is this happening in between the iterations or at the beginning of optimization?

 

could you please share the .out file?

Thanks for replying and Happy new year!

I'm using the free shape optimization. It  happened between the  iterations.

 

 

Some of the .out  is as below:

==================================

 OPTIMIZATION HAS CONVERGED.

 FEASIBLE DESIGN (ALL CONSTRAINTS SATISFIED).

 THE GLOBAL SEARCH OPTION FOUND A NEW UNIQUE DESIGN.
 THIS IS ALSO THE BEST DESIGN SO FAR.


 OPTIMIZATION HAS CONVERGED.

 THE GLOBAL SEARCH OPTION DID NOT FIND A NEW UNIQUE DESIGN.
 THIS DESIGN HAS BEEN FOUND 2 TIMES SO FAR.

 Element # 3473, element type QUAD4.
