enGrid - Numerical Method Implemented for Mesh Generation
 
Greetings All

Could someone please let me know which numerical schemes are implemented by the enGrid package - for study reasons and there is limited information available on the software.

As I understand it the model is based upon NetGen, however there appears to be some differences between results and I read that NetGen does not generate boundary layers.

Any assistance will be greatly appreciated.:confused:

Good work with the software guys, hope to see continued development. The one thing I did find quiet beneficial is to export the Blender model out to Meshlab or Netflabb and then reimport into Blender. This solved a lot of issues with odd shaped faces and 'watertightness' in Blender

Regards
JFM

enGrid is an open-source mesh generation software with CFD applications in mind. enGrid uses the Netgen library for tetrahedral grid generation and an in-house development for prismatic boundary layer grids.

So can you elaborate on what exactly you want to know?

Thanks for sharing the info! Although I thought that Blender should also be able to fix surface meshes on it's own, although perhaps not as interactively easily as in Meshlab...

Best regards,
