Dear All,
I am currently using SolidWorks Flow Simulation to simulate an heat exchanger (air/water). I am facing an issue, indeed the heat exchanger is very big (100 tubes, 23m length each). The flow part is possible to simulate, however, when i try to add the heat exchange the number of cells becomes crazy. Particularly, the number of cells in the solid parts. However, my goal is to focus on the flow part and the influence of temperature on this flow. Thus, the solid conduction parts is not very interesting but i can not reduce the number of cells in the solid, it seems to be fixed and imposed by the mesh generator. Do you have an idea about how can i reduce the number of cells ?

Thank you !

Best regards,
Pierre
