Distorted elements

Posted by Chhavi Kusum at March 25. 2020

Hello all,

I am creating several 2D submeshes on my geometry before creating the 3D mesh. 

For the 3D mesh, I use the 1D-2D-3D NETGEN Algorithm.

My submeshes use, the MEFISTO algorithm, NETGEN 2D only and NETGEN 1D-2D.

The 2D elements are generated well, but when the 3D elements are generated they are distorted/contorted and just all over the place, see attached for picture of the mesh.

I dont understand what is going on and the reason for this.

Hi

It's hard to say what is wrong. Try NETGEN 3D instead of NETGEN 1D-2D-3D.

Hello

Could you share your geometry for debug, via a private message.

Best regards

Edward

Thanks for your suggestion. I tried NETGEN 3D with NETGEN 1D-2D. That worked. Would you happen to know the reason for this?

First of all, avoid MEFISTO. NETGEN is much better.

Thanks, I have seen this said several times. For my geometry, for some faces, the mefisto works very well and netgen fails.
