Hello
For a co-simulation with Fluent and Twin Builder (and in general), Fluent needs to receive Real values and it sends back Real values to Twin Builder. In Twin builder, you need to define sensors and sources for this interaction.
The figure above is from the online help (Product Coupling - Fluent - Overview). The mass flow rate from the loop is measured using a sensor and the value is passed to the proper pin in Fluent, heat is supplied from a constant block. Fluent calculates the temperature and passes it to Twin Builder through a temperature source (using a pin).
I would recommend first creating a circuit with only the placeholders for the Fluent co-simulation pins (imagine the above diagram with the Fluent component removed and everything else the same), you could use constant blocks to mock the signals coming out of Fluent, and verify that your circuit works. Then, proceed to connect to Fluent.
