Documentation about mesh
Hello everybody,
I am thermodynamic engineer.
I would like to make a thermal analysis of a model but, even if I know some stuff about FEM, I still do not know when it is better to use tetra or hexa and linear or quadratic approximation.
Could you please give me some good link to read more about how to pick the best choice ?
Thank you very much.
While I cannot give you a source (straight from memory), I remember that triangles and tetrahedrons are favored by Code_Aster for thermal simulations. Give the CA forum a thorough search, and it'll turn up

Thank you very much,
So it depends on the software I use, and not only the study I do ?
I will take a look to the Code_Aster forum, I went there because I wanted something all-round.
Syrthes 4(.0.1) is available now, and I've just installed it. It is a huge step over the old version 3. Syrthes is specifically for thermal calculations - it can even be coupled with Code_Saturne. Syrthes only accepts linear tetrahedrons (or triangles fro 2D)
