Benchmark Model
A 10x6 mesh configuration is created with QUAD4, QUAD8, TRIA3 and TRIA6 elements. One edge of the plate has a prescribed temperature of 100 °C, one end is insulated, and there is convection to the ambient temperature at the other two edges.
The material properties are:
- Material Properties
- Value
- Conductivity
- 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).
| Shell Element | Material Temperature at Point C, x=0.08m, time t=32sec (°C) | Normalized with the Target Value |
|---|---|---|
| Quad4 | 17.77 | 1.029825549 |
| Quad8 | 17.1 | 1.070175439 |
| Tria3 | 17.29 | 1.058415269 |
| Tria6 | 16.83 | 1.087344029 |
