What does this mean?  "Error: Jacobian of element non-positive; Element numbering may be in incorrect order or element may be highly distorted."

 

I'm flabbergasted, maybe someone can enlighten me?

 

Thanks in advance.

negative jacobian means mostly you got a distorted element.you must be using solid elements.you can check the particular element number and cross check the mesh sizes.

Nope, I'm sorry. I once more meshed it, then it came out fine. So it was probably some hick -up. Which I experience quite a lot these times.

Now it only doesn't converge, but that's normal.  *sigh*
