Reply To: Coupling Fluent with other simulation softwares such as TRNSYS.

Hello,

I don't have experience experience dealing with such coupling, but from previous studies I could see that this coupling can be done via a script and results file. TRNSYS controls this whole coupling as it is easier to integrate new components in TRNSYS. 

A script file is a *.in file, created by TRNSYS that is read by FLUENT. It contains the journal file with all the inputs to the CFD simulation: specific models to be used, updated boundary conditions, and which outputs to be produced. A results file is a *.txt file, created by FLUENT containing the outputs from the CFD tool. These outputs can be localised or mean values. 
Check with TRNSYS about generating script file to be used for such coupling.

You can refer to following studies for reference:

• Coupled TRNSYS-CFD simulations evaluating the performance of PCM plate heat exchangers in an Airport Terminal building displacement conditioning system.
• Advances on the coupling between a commercial CFD package and a component-based simulation program.
