Hello!
I'm working on 3d LES FV code for NS. I've already made a fine solver for structured grid, and now my task is to do the code for tetrahedral elements (unstructured grid). And now i'm facing the problem of calculating geometry properties of a tetrahedra. I know that many people already did it b4, so i hope you can help me with links on computational geometry or good advices. Thank you in advance! |

Dear Dr. Nick,
You could refer to the book by Hirsch, which gives the area normal and volume computations for different elements Regards, Ganesh |

Ferziger/Peric page 224 (1st edition) should be give some ideas.

Thanks!, though I already found the solution by reading my old university lectures on 3d geometry and topology =)
