Triangles, BEAM4T1

Mesh: Eight triangles--see appendix A.2.

Material properties: $\lambda=20$ W/mK.

Boundary conditions:

$\alpha_1=\alpha(T_{w1})$ W/m²K, $T_1=-20^\circ$C
$\alpha_2=\alpha(T_{w2})$ W/m²K, $T_2=25^\circ$C

$$\alpha(T)= \left\{\begin{array}{ll} 30 & \mbox{for}~T \le 0... ...T\in (0,0.1)\\ 10 & \mbox{for}~T \ge 0.1 \end{array}\right.$$
