The heat conductivity is 1.0W/m degC. As to the boundary condition, the room temperature 100degC and the heat transfercofficient 0.0002W/m²degC are assumed on the surface indicated by arrows, and the room temperature 20degC and the heat transfercofficient 0.0001W/m²degC are assumed on the other surfaces. All the elements are the quadratic tetrahedral.
