Transition elements, BEAM71T2

Mesh: Two hexahedra, two semi-loofs--see appendix B.4.

Material properties: $\lambda=20$ W/mK, $\rho\!\cdot\! c=3\times 10^6$ J/m³K.

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

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

Initial conditions: $T(x)\equiv 25^\circ$C at time t=0.
