Fluent or CFX if Ma >5 ?
Hi,
If I want to simualte a case with Ma >5, which software is better, Fluent or CFX? Or another one? Thanks. yflin |

Hi,
I heard that the energy equation is buggy in CFX. This can be tested on an simple throttle where enthalpy should be constant but it's not with CFX. I repeat: This is what I heard but I haven't tested on my own. If true, you'd prefer Fluent for Ma > 5 - Alan |
Re: Fluent or CFX if Ma >5 ?
Certainly Fluent is the best, if Ma>5 then it can involve a thicker turbulent BL that SST (code CFX employs) many not be as effective as RNG k-E Method (code Fluent Employs).

Or of course you could use STAR-CCM+ which has got a nice coupled solver and both SST and K-E
