Thermal - Structural Analysis. I'm new in flow simulation. One of the most common applications of Flow Simulation today though is thermal analysis for predicting cooling performance of electronics and other heat generating components. This is an internal analysis with default outer wall condition (heat transfer coefficient =7w/m2K). As the thermal performance of such systems is often dominated by conduction and convection, radiative heat transfer is often assumed to be minor and neglected in the simulation to reduce solution time. Mesh Refinement around Heatsink. For a summary on thermal loads and restraints, see. Watch how SOLIDWORKS Simulation enables you to evaluate steady-state thermal performance and heat analysis over time. As a refresher, thermal analysis in SOLIDWORKS Simulation Professional allows for simulation of all 3 modes of heat transfer as either steady-state or time dependent.
