4619+
A slab of thickness $L=0.01$~m with a conductivity of 10~\si{W/(m.K)} is exposed to a backside temperature of $T_g=200$~\si{\degree C}.
4620+
The backside heat transfer conditions are $h$=50~\si{W/(m^2.K)} and $e$=0.5. The frontside heat transfer conditions are $h$=10~\si{W/(m^2.K)} and $e$=1.
4621+
This case test that both sets of conditions are applied.
