h1. Physics Setup


h2. Material Properties


h4.

At this point, the material, "Cornellium", will be assigned to the geometry. Then, ANSYS will know the value of k, the coefficient of thermal conductivity, to use in the boundary value problem. To assign the material, expand {color:#990099}{*}{_}Geometry{_}{*}{color}, !geom.PNG!, in the tree outline. Next, click on {color:#990099}{*}{_}Surface Body{_}{*}{color}, !SurfBody.PNG!. Then set {color:#990099}{*}{_}Assignment{_}{*}{color} to Cornellium in the "Details of Surface Body" table, as shown below.

h2. Adiabatic Boundaries


h4.

The top and left edges of the rectangular domain are perfectly insulated. In order to incorporate these boundary conditions, first {color:#990099}{*}_(Right Click) Steady-State Thermal > Insert > Perfectly Insulated{_}{*}{color}, as shown below.

Next, hold down *Control* key and click on the top and left edges of the rectangle. Holding down the *Control* key lets you select multiple items. Then, {color:#990099}{*}_(Click) Apply{_}{*}{color} in the "Details of Heat Flow" table.

h2. Isothermal Boundary


h4.

The bottom edge of the rectangular domain has a constant non-dimensional temperature of {latex}$\thetatheta${latex}=1. Recall that we are specifying the dimensional problem in ANSYS such that the dimensional and non-dimensional values of temperature are the same. To implement this boundary condition, {color:#990099}{*}_(Right Click) Steady-State Thermal > Insert > Temperature{_}{*}{color} , as shown below.

\\
Next, click on the bottom side of the rectangle and {color:#990099}{*}_(Click) Apply{_}{*}{color} in the "Details of Temperature" table. Then, set {color:#990099}{*}{_}Magnitude{_}{*}{color} to 1 degree Celsius as shown below.

h2. Convective Boundary


h4.

The right side of the rectangle has a convectiveconvection boundary condition. To implement this boundary condition, {color:#990099}{*}_(Right Click) Steady-State Thermal > Insert > Convection{_}{*}{color} , as shown below.

{newwindow:Click Here for Higher Resolution}https://confluence.cornell.edu/download/attachments/146918515/InsConv_Full.png{newwindow}\\
\\
Next, click on the right side of the rectangle and {color:#990099}{*}_(Click) Apply{_}{*}{color} in the "Details of Convection" table. Then, set the {color:#990099}{*}{_}Film Coefficient{_}{*}{color} (i.e. convection coefficient, _h_) to 5 W/(m^2 C) and set the {color:#990099}{*}{_}Ambient{_}{*}{color} temperature to 0 degrees Celsius, as shown below. As we saw in [Pre-Analysis|SIMULATION:2D Steady Conduction - Pre-Analysis & Start-Up], these dimensional settings correspond to a Biot number of 5.

This concludes the setup of the boundary value problem. We can move on to obtaining a numerical solution.
