cfx solvers FVM?
Is cfx all FVM based?

Re: cfx solvers FVM?
Yes. CFX uses an element based Finite Volume Method.

Re: cfx solvers FVM?
The PI sheet for cfx5 states the following "Conservative finiteelement based control volume method"
This implies FVM?

Hi Derrek
CFX5 uses an unstructured Finite Element based Finite Volume method. The FE basis comes from the use of shape functions, common in FE techniques, to describe the way a variable changes across each element. It is also a node based code, where the solution variables are solved and stored at the centers of the finite volumes, or the vertices of the mesh. I believe TASCflow employs a similar strategy, except that it can solve on only blockstructured hexagonal meshes. CFX4 uses a cellcentered Finite Volume/Finite Difference method. Sharks

sharks, thanks for the info.
I am not that familiar with the FVM. Still not sure where the finite volume comes into play in regards to cfx4. If it is an unstructured mesh using shape functions, how does it differ from a true FE based solver? cheers, derrek

Hi Derrek,
A control volume is analagous to the finite volume. Six of one, half a dozen of another. Regards, Robin
