ANSYS Fluent FSI tutorial
Hi everyone,
I have two main problems: 1) I am trying to simulate blood flow in the vessel by using ANSYS Fluent FSI but since I don't have any tutorial or document about it, that study is very difficult for me. If there is any tutorial about ANSYS Fluent FSI, can you please share or give a link? 2) What is the main difference between 1 way and 2 way FSI simulations? |
Fsi
Ansys has tutorials listed on their website. Admittedly the new customer portal is awful and hard to find things but they are on the portal. I do warn however that my colleage recently did a trial of fsi with fluent and claimed that it was FULL of bugs and problems. Supposedly these issues will be worked out in ansys 15 but he was unable to get a single simulation working I ansys with the help of several skilled support engineers.
One way coupling means that pressures are passed from fluent to mechanical and are then used in a structural analysis. Two way coupling means that forces are passes to mechanical and displacements are calculated. Then those displacements are passed back to fluent and through dynamic meshing, the mesh updates. This is what you want for blood flow. Hope this helps. Good luck |

I use 14. He used 14.7.5. In one of our recent meetings he has mentioned that he has found tons of bugs and errors and complications in 14.7.5 especially in meshing, which is odd because it was supposed to be way better. I use 14 with no problems. Apparently the download file for 14.5 (which is different than 14.7.5) is no longer available.

How to set up an FSI project
Please I am some how new to FSI, I will to know the best possible way to setup such a project in Ansys or recommend a place to have more knowledge on it.
Thanks in advance. |
Please see my first post which directs you to the customer portal

Thank you MachZero for your keen interest. If Fluent is problematic with FSI, is CFX suitable for FSI simulations?

Hard to say. Ansys had CDC working with fsi before they did fluent so maybe. Honestly I don't know since I haven't tried fsi on either platform personally. Please let me know what you find out of you try. I am told abaqus works "seamlessly" with star ccm. Maybe try that too
