1. Coupled Transient Cooling Fin Estimated Time for Completion: 5 minutes Experience Level: Higher MSC.Marc 2005r2 MSC.Patran 2005r2

2. 2 Topics Covered Creating 2D solid elements using Plane Stress Creating Thermal-mechanical material properties Creating Convectional boundary conditions Applying Adaptive Thermal Increment Type Applying Coupled (Thermal-Structural) Analysis

3. 3 Problem Description A planar slab of material is subjected to heat loads and the resulting transient response is determined. Even though the thermal efficiency may be better with the cooling fin, the structural response may not. Therefore in this example, a coupled heat/stress analysis is applied.
