Example - 2D steady-state thermal analysis
• Domain - 0.6×1.0 meters.
• Boundary conditions:
– The left boundary is insulated.
– The lower boundary is kept at 100 °C.
– The upper and right boundaries are convecting to 0 °C with a heat transfer coefficient of 750 W/(m2°C).
• Material Properties
– Thermal conductivity is 52 W/(m °C).
– Density, ρ - 7850 kg/m3
