Here

{latex} $x_D$ {latex}

and

{latex} $y_D$ {latex}

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

{latex} $\theta$ {latex}

. For the geometry, we pick

Launch ANSYS Workbench from the Start menu as shown below.

Management of Screen Real Estate

This tutorial is specially configured so that the user can have both the tutorial and ANSYS open at the same time as shown below. It will be beneficial to have both ANSYS and your internet browser displayed on your monitor simultaneously. Your internet browser should consume approximately one third of the screen width while ANSYS should take the other two thirds as shown below.

If the monitor you are using is insufficient in size, you can press the Alt and Tab keys simultaneously to toggle between ANSYS and your internet browser.

The problem at hand is a steady state thermal problem, thus the steady-state thermal analysis system will be used. Click on Steady-State Thermal(ANSYS) as shown in the image below.



Continue to hold down the left mouse button and drag Steady-State Thermal(ANSYS) into the Project Schematic area. You will then see a green rectangle appear as shown below.



Drag Steady-State Thermal(ANSYS) to the green box which will then turn red and contain text saying "Create standalone system".



Now, release the left mouse button to create the standalone system. Your Project Schematic window should look comparable to the image below.



Lastly, rename the system to "2D Steady Conduction", as shown below.

Engineering Data

In this section the material properties that appear in the boundary value problem will be specified. In our case, the only material property that appears in the boundary value problem is k, the coefficient of thermal conductivity. ANSYS requires a name for the material, so we'll call it "Cornellium". First (Double Click) Engineering Data. Then click in the cell that contains the text "Click here to add a new material" and type in Cornellium as shown below.

Next, (Expand) Thermal and (Double Click) Isotropic Thermal Conductivity, as shown below.



Then, set the value of the Isotropic Thermal Conductivity to 1 W/(Mm*C) as shown below.
