and

are the dimensional coordinates. We will choose the dimensions and boundary condition inputs such that the dimensional problem matches the non-dimensional one. Then, Tvalues in Celsius that ANSYS reports can be interpreted as

. For the geometry, we pick

\[ 
W = 1m, \ \ H = 2 m
\]
{latex}

For the boundary conditions, we pick

Wiki Markup
{latex}
\[
T_0 = 1, \ \  k = 1, \ \ T_\infty=0 \ \  h =  Bi
\]
{latex}

These are the inputs we'll use while setting up the problem in ANSYS.
