Delaunay mesh fail
 

Hi everybody,

I'm currently trying to generate a proper mesh for a vascular CFD simulation.
The geometry is quite complicated but I have been able to obtain a tetra/mixed mesh through a robust-octree algorithm without any kind of problem detected by the ICEM check mesh tool.

The problem arise when I try to convert the mesh into a Delaunay one starting from the existing mesh just generated.
The process fails in the most cases and, when it doesn't, the generated mesh presents a very huge number of decets and errors.

Does anybody has any idea about the reason for this?

Thanks,
Niccolò

Hello,

Were you able to find a solution for this problem? I am also facing a similar issue.
