EX_HEATTRANSFER5 2D Transient cooling shrink fitting example.

[ FEA, OUT ] = EX_HEATTRANSFER5( VARARGIN ) This example models transient cooling for shrink fitting a two part assembly. A tungsten rod heated to 84 C is inserted into a -10 C chilled steel frame part. The time when the maximum temperature has cooled to 70 C should be determined. The assembly is cooled due to convection through a surrounding medium kept at 17 C and a heat transfer coefficient of 750 W/m^2K [1].
