$x_D$ |
and

$y_D$ |
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

$\theta$ |
. For the geometry, we pick

\[
W = 1m, \ \ H = 2 m
\]
|
For the boundary conditions, we pick
| Latex |

\[
T_0 = 1, \ \ k = 1, \ \ T_\infty=0 \ \ h = Bi
\]
|
These are the inputs we'll use while setting up the problem in ANSYS.
