Reply To: Do structures in the fluid domain have to be coupled to ICFD?

[Reno Genest]

Hello Chan,

To have an FSI interaction between the ICFD fluid and the structure, you need the following keywords:

*ICFD_CONTROL_FSI

*ICFD_BOUNDARY_FSI

If you don't include the above keywords  in your model, the baffle structure should not interact and influence the ICFD fluid.

You will find video tutorials on ICFD FSI here:

And on DEM coupled with ICFD:

To couple the DEM particles to the ICFD fluid, you need to following keyword:

*ICFD_CONTROL_DEM_COUPLING

 

Let me know how it goes.

 

Reno.
