Hello,

generall opinion seems to be that:

FEM based solvers are less efficient (speed) and less accurate (balances of conservation quantities)

what do you seasoned guys say?

FVM based solvers are more FUNNY, that's the difference.

FEM provides a continuous (up to a point) solution.

FVM is generally considered easier to program than FEM, but opinions vary on this point.

In FVM The resulting system of equations usually involves fluxes of the conserved variable, and thus the calculation of fluxes is very important in FVM.

FVM are generally expected to provide better conservation properties.

one particular method of CFD can not be applied to all the problems but the best way is not do generalization that one form is better than other but to do some riview of the previoius work for the specific problem u r dealing with.

hope this helps Regards

happy to receive qualified opinions from seasoned guys. Generalizations aren't the target.

Scope of problems for which experience based opinions relating to the original question is seeked for (wrt which opinions are of primary interest):

sub to trans/supersonic, in/compressible, single phase w and w/o CHT under two-equation turbolence models.

Hi I think(my point of view): FVM is better than FEM in problems governed by diffusion as non premixed turbulent combustion flames (combustion reactions depends on micromixing of oxidant and fuel)...however I couldn´t generalize it because of depending on other reasons as interpolation schemes, kind of FVM, coordinates system, linear eq solver...etc.. It is only my opinion... very interesting topic... I hope opinions from CFD experts regards
