Hello,
I have a query regarding the conjugate heat transfer probelm. I am solving a laminar flow ("laminar flow" interface) problem with a solid heat source heating the fluid. So I used "heat transfer in solids" interface with fluid domain explicitely defined inside. This is an incompressible flow with all fluid and solid properties being constant.
To couple the heat transfer between solid and the fluid, I explored two options. 1. Use "Flow coupling" in multiphysics 2. Inside the "heat transfer ..." interface, where I define a fluid, I can specify different "Model Inputs" - and I specified the "spf" velocity field.
However, these two methodologies are giving me different temperature fields. Could you please let me know the difference between these two approaches?
