I'm working on a project to implement ibm in fluent for simple test cases, like flow over cylinder. I figured out that we can add a source term using udf to the momentum equation as reqd by ibm.But I'm not able to fix lagrangian points where these force terms must be added. Ansys uses body fitted mesh , is it really possible to use a cartesian mesh and use a lagarangian method to track the solid ?
Hello,
Thank u guys, Have been working on IBM for a week (Couldn't come online) . As u guys rightly said It's difficult to implement it. But fluent has a add on package for immersed boundary method develeoped by cascade technologies .

I wonder how these guys figured out how to implement IBM in fluent.
In openFoam its possible , but I'm not familiar with it !
I guess, you can not use cartesian meshing using any Commercial package. But, still kindly check with their respective forums.
There is a possibility of using this methodology in Open Foam.
I don't think its possible as FLUENT employs a mesh that is conforming to the body, whereas IBM relies on exactly opposite.

Hi,
I think the commercial CFD software (i.e., FLOW-3D) using a similar method (FAVOR) like IBM. You can have a try!
Hi ,
I don't think that you can use IB in fluent . As the IB method requires Eulerian and Lagrangian space declaration and force transformation in Laplacian space between the fluid and the elastic body you consider. As far my knowledge is concerned FLUENT is based on Euler based as the CFD solvers usually are.

Did you manege to implement IB in Fluent? if you have any supplementry documentation please share.
Thanks in advance
Hello Hassan,
I'm working on something different. Haven't worked on it after my internship.
Thank you for your answer.
if you have any clue about how to use it,
please let me know
