Error #15 negative jacobian

David_21639

Hi, 

I want to calculate my meshed model, but the Program tells me that there is a Error#15, negative jacobian at one of my elements. 

Tried to remesh it a couple times... but it doesn´t work... 

What can I do to fix this problem? 

I tried to set Param<Checkel_V1 to "no" but that didn´t solve my problem.  

 

sincerely, 

David

probably there's some part of your model that is failing the jacobian quality test, that even checkel_no can't ignore it.

Can you check your model for failed elements (F10 >> check elements)?

Find the ones with poor jacobian values and correct that region in the geometry or in the mesh directly, depending on your HM skills.
