Input Mesh is self-intersected

Dear all,

 

I am a beginner in Hypermesh and I wish to convert a 2d surface mesh to a 3d solid mesh. My model consists of a small part of the mandible and is complicated. I have tried to refine the meshes and solved the free-edges problem which appear to be the first problem I faced when I tried to convert the surface mesh to a solid 3d mesh. But now, I faced another error : 'Input Mesh is self-intersected'. 'Boundary recovery: failed sub grid recovery...'. 

 

I chose the option:

1) Smooth Pyramid

2) Fix comp boundaries

3) update input shells

4) mesh to current comp

 

I have spent months trying to mesh this model. It would be great if someone can lend a helping hand to me!!! Thanks in advance.

 

Cheers,

Mushi
