Greetings Joel,

Thanks for inputs! I've used NegGen 1D-2D-3D as suggested by you before on the forum as well and stand-alone meshers - Gmsh and NetGen - without success.

I'll try dividing the geometry into volumes, mesh and then stitch in Code-Saturne. Are there any tutorials or guides to do this? I couldn't locate and seek your inputs on how to proceed in this regard.

Once my project is in public domain, I'd be more than happy to cataloge my open-source journey and share it here with a hope that it'd help. I've turned a CAELinux Fan!

Thanks!
Best Regards,
Pranav

Greetings All,

I'm now trying OpenFOAM. For k-epsilon, I used an online calculator : anisonyan.com/keps/
I used Saturn to check Mesh Quality and it reports 15% of my cells are bad in Category 3: Least-square, a few are also bad in Category 0: Orthogonality. I used Netgen 1D-2D-3D for grid generation.

In OpenFOAM I get the following error output. Could somebody point me in a direction I could proceed?

Thanks
Best Regards,
Pranav
