What is the meaning of via system coupling in wall boundary condition?
Hey guys. need help here because i have been confused a lot in system coupling in ANSYS Fluent. i was going to couple my fluid model in fluent into steady state thermal. so i set the wall boundary condition for thermal to via system coupling.
Then, there is an input there which is the heat generation rate. so i was confused, does the heat generation rate is coming from the fluid or coming from the outer region??
Really need your help!!
