Desperate student needs help meshing 3D GAMBIT model - please help!
 
Hi there,

I found this forum when google-ing for help with 3D meshing on Gambit. I am currently a mechanical engineering student in my 4th year and my project involves CFD analysis of wind velocity profiles over North Sea oil rigs.

I am currently trying to mesh the model in GAMBIT and having difficulties that I am unsure how to solve. I first tried meshing the faces, however when I tried to then mesh the volume Gambit complained about highly skewed elements preventing the volume meshing from taking place - no matter how fine or coarse the face meshing was.

Then, under suggestion from my supervisor, I tried to just mesh the volume, without face meshing first. This almost worked, but at the end Gambit kicked up a fuss again and from what I gather was complaining about poor face meshing and telling me to go mesh the faces - which I know doesn't work either!

Can anyone offer any help or advice here? It would be greatly appreciated! Thank you.

Check the messages from Gambit as it failed to mesh some surfaces. Remember face number, and display those faces.
It should have small angle, small edge etc...
Just use split/merge tools to workaround those issues.
If you still have problem, post pictures.
