Export Fluent and Import it to Comsol

I have a flow on a porous medium and overlying water column.

Ideally, I want to simulate the flow in the water column by FLUENT, then export the data to COMSOL (pressure,v....) to simulate the flow in porous medium with COMSOL. Flow is unsteady. Maybe there will be a loop because porewater flow might affect the flow in the water column.

I have heard that it is not possible to export FLUENT to COMSOL. Any recommendations or other CFD code to use?

Thanks for helping and suggestion.
