Dear all,
I have a fluid that flows within a tube. There is a structure inside of tube which made of different material. My question: is it possible to model this problem in Fluent? or should I move to fluid-structure interaction analysis? Actually, I tried to solve using Fluent, but it didn't recognize surfaces of the internal structure as wall, but as interfaces, and hence, I wasn't able to run the program. Any help would be appreciated! |

Hi, did you try to subtract the structure from the fluid domain by using boolean ?.

Dear Jumaah,
Yes, I did subtract the internal strcuture from fluid. The geometry is fine, I think. Even, I was able to name each part using "named selection" tool. |

a kindly reminder. In fluent setup, if you have one zone that is recognized as fluid under cell zone condition, from boundary conditions you can change the BCs type.

Problem solved, thanks for your comments.
I had to define the interface between two surfaces, one from structure and another from the fluid that completely overlapped to each other. Thanks. |

Dear Pachi,
Validation depends on your problem type. Mine was a vetricular assited device and I used some pubolications from the literature to validate my results. |
