Problem with mesh generation

Nestor

Hi there,

I've got a problem while trying to mesh a volume. I just want to know what this means:

"Initialization failed; perturb boundary nodes and try again.

Initialization failed to mesh 1 nodes. ERROR: TG_Mesh_Domain failed with error code 1. ERROR: Tetrahedral meshing has failed for volume entrada. This is usually caused by problems in the face meshes. Check the skewnesses of your face meshes and make sure the face mesh sizes are not too large in areas of small gaps."

The 2d elements' skewness are below 0.8, and the most part below 0.6. I've made sure that, more less, in the zones with small elements, there are other elements of the same size. But I don´t get any good result.

The former 2d meshes for the volume are Tri Pave based.

Any suggestion?
