Benchmark Model

A 10x6 mesh configuration is created with QUAD4, QUAD8, TRIA3 and TRIA6 elements. One edge of the plate is having a prescribed temperature of 100°C, one end insulated and convection to the ambient temperature at the other two edges.

The material properties are:
Material Properties
52.0 W/m°C
Surface Convective Heat Transfer Coefficient
750.0 W/m2 °C

Linear Static Analysis Results

All results are normalized with the target value (18.30°C).
