[destroy]

Dear all,

I am using the fluid-structure interaction (FSI) approach with coupling of Mechanical and Fluent. It is working by transferring data (integrated pressure, displacements etc.) between solvers by multiple so-called coupling iterations.

Recently I discovered, that Fluent itself has an option to use build-in simple structural solver to facilitate FSI simulation. I will use this approach and compare the results with the standard approach described above. However, I do not understand, and I did not found the information in theory guide, on how the intrinsic FSI solver works. I mean, are there any coupling iterations? Or there is created a monolithic matrix, as in monolithic solvers such as Abaqus?

Kind regards

Hello I will not be able to comment on solvers such as Abaqus here. But, if you need information on the Intrinsic FSI (its capabilities and limitations), please have a look at the following link.

Hello Karthik

I am not able to access the above link. I think it requires customer login while I am using academic license.

 

Thank you
