Hello, I'm getting this error. "CTETRA element 94816 is distorted (zero or negative Jacobian)."

What can I do, will you answer me as soon as possible? I was always applying mesh in the same way, I couldn't understand why I got this problem now.

Regards,

    can you take a look at the element 94816? have you performed element check in HyperMesh?

    Is your mesh ok? You should probably take a look at this particular element, isolating it, verify if it is ok or not.

    Not recommended, but you can try to bypass the element check by using PARAM,CHECKEL,NO. This would make OptiStruct ignore some element checks. But again you should first take a look at your mesh, if it is ok.

     

    What kind of analysis are you performing? Some pictures might be helpful as well.

    Also, always share the .out file of your run.
