Default Meshing problem

Dear Sir, When I was meshing runner of Francis turbine (hydro turbine) using Tet/Hybrid-TGrid scheme(volume meshing), GAMBIT shows following message. "Initialization failed, perturb boundary nodes and try again."

What does it mean? and how to solve it?

Is it necessary to mesh first line then face and then finally volume?

Waiting for valuable reply.

With regards

Sanjay Jain

Check your geometry: If you have small edges, small angles between edges, etc... Gambit will return you this kind of message. You should clean up your geometry.
