Example Heat Transfer in a Slab

Consider the problem of heat transfer in a slab with no internal heat generation but with a thermal conductivity that varies linearly with temperature - Eq. (9.1) with the following parameters  

Step 1 Choose ID, then Chemical Engineering, then Energy Balance, then Conduction. 

Step 2 Create the line by clicking on the line icon. Then move the cursor to the beginning of the line and draw to the end. 

Step 3 Define the mesh by clicking on the triangle symbol. First 15 elements are created, with 31 nodes. Successive clicks to refine the mesh give 61 and 121 nodes. 

Step 4 Specify the parameters for the differential equation. Choose Physics/Subdomain Settings to see the equation
