Dear members
I am carrying out LES simulation. The solution converges for URANS but doesn't when I switch to LES. I find a lot of people using FLunet rather than CFX for LES simulations. I think Fluent would provide advantages of being able to use cut cell meshing and providing synthetic turbulence at the inlet. Hence I ask is it better to use fluent for LES ? What advantages are there using Fluent ? |

what do you mean for "but doesn't when I switch to LES"?
You can also consider that OpenFOAM has some LES modules. |

LES are typically transient calculations with large meshes, so calculation cost is important. CFX per iteration is slower than Fluent, this is why there is possiblity that Fluent is chosen over CFX. |

Hi
I have been using Cradle's SC-Tetra for my CFD simulations. This has been overall good software to me for a variety of models. This has a module for LES and VLES. |
