Model Description

An aluminum heat sink with fins, which is modeled using solid elements and has a convective heat source at one end and the ambient temperature is maintained zero. Total volume responses and a thermal compliance responses were created. The objective is to reduce the thermal compliance by changing the density of the elements. A design constrain is defined for volume response with an upper bound value of 93000.
