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.
- Objective
- Minimize the thermal compliance
- Constrains
- Upper bound on total volume response
- Design Variables
- Density of each element in the design space
