CFX or STAR CCM

plum1 · March 16, 2011, 05:40

Hi All
We have been using Ansys CFX for modelling a wind turbine. We have been told it is better to use STAR CCM for this purpose. Is this correct?
Many thanks

Not necessarily it depends on number of factors. What exactly are you looking to analyse?

Both codes have their good points and their bad points but in this specific area with no further information i wouldn't expect much difference between the 2 to be honest.

Can't comment on STAR, but CFX is generally accepted as the best turbo code. The turbulent transition model + SST developed by CFX is also used on large wind turbine blades and gives more accurate torque results - this may not be available in STAR. If FSI becomes important then CFX has a better approach than STAR.

Let me guess - by a Star sales person?

Why not trial both codes and run your simulations and work it out for yourself. That is the best way.
