Hi everyone,
I have worked to achieve my project by using fluent but I have to switch to star ccm+. I use LES to solve two phase air-water flow. I understood that converting from tetrahedral to polyhedral will decrease the skewness and improve the meshing quality. My question can I switch to polyhedral from tetrahedral which I used it in the fluent file? does that effect the geometry or need to create computational domain by star ccm instead that used in fluent? Thanks for all. |

thanks Lane very much for your reply, I appreciate your effort and your cooperation.
Just to let you know that I create my geometry which is simple but I need to refine certain volume through cubic volume that I failed to achive it by star ccm so I switched to ICEM instead to create this geometry and refine the mesh. my question is can I import the icem file before meshing to star ccm or as some people advice me I have meshing it by ICEM and Create FLUENT file then import it to star ccm? Thanks so much Lane. Last edited by Afaraj; August 21, 2016 at 16:05. |

export in fluent 6 format
and import 'volume mesh' in ccm Quote:

Personal preference matters. Importing isn't a problem, so use whatever you like. I prefer the ICEM mesher over the Star-CCM mesher any day. Star's meshing algorithm went on a fork early in its history and tends to produce 'ugly' meshes. The way it retracts prism layers is such a huge annoyance. It also likes to throw all the skewed cells right at the prism layer and core mesh interface, the worst place to put them.
