[Gmsh] Documentation about tetra hexa element ? Linear or quadratic ?

[Adrien Girard]

Hello everybody,

I am thermodynamic engineer.

I would like to make a thermal analysis (conduction, convection, radiation)
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.
