Two-dimensional modeling of heat conduction using ANSYS

Here are the steps for setting up the model:

 
Model Development:

ansys -g -j thermal &

1. Set Preference:
    Preferences - Thermal = on - OK

2. Define a square region:
   Preprocessor - Modeling / Create - Rectangle - By Dimension
   X1=0.,X2=0.305
   Y1=0.,Y2=0.305
   OK

3. Define materials
 Preprocessor - Material props - Materials Model 
  - Thermal - Conductivity - Isotropic - Thermal conductivity = 200.0 - OK
 OK

4. Select Mesh Type:
   Preprocessor - Element Type - /Add/edit/Delete - Add 
   Select "Thermal Solid" and "Quad 4node 55"
   OK 
   Close

5. Meshing:

  Preprocessor - MeshTool - 
  Size controls/ lines/Set  - 
  Pick x=0 and y=o lines - NDIV = 16 - OK 

  set Mesher = Map
  Mesh - Pick the area - OK 

6. Apply BCs and loads:
 
Solution - Loads/Apply - Temperature - On Lines
Left click the x=L line - OK
Value = 20 - OK
On Lines - Left click the y=L line - OK
Value = 30 - OK

Loads/Apply - Heat Flux - On lines
Left click the x=0 line - OK 
Value = 10000 - OK 
On Lines - Left click the y=0 line - OK
Value = 15000 - OK

7. Solve

Solution - Solve/Current LS - OK

8. Plot temperature distribution on a line for comparison
    with analytical solution

Define a path:
-------------

General Postproc>Path Operations>Define Path>By location>Name=ycenter, nDiv=16,OK
  >NPT=1, X=0.,y=0.1525, z=0, OK> NPT=2, X=.305,y=0.1525, z=0, OK> Cancel

Map the variable to be plotted on the path:
------------------------------------------

General Postproc>Path Operations>Map onto Path>Lab=T, Selection=Temperature>OK

Plot the results:
------------------

Utility Menu>Plot>Results>Path Plot>Select T>OK

Save the data for comparision with analytical results:
------------------------------------------------------

Utility Menu>List>Results>Path Data>Select XG,T>OK
File>Save as>results16.dat>OK>close

9. Contour plot

General Postproc>Plot Results>Contour Plot/Nodal Solu >OK

Note: For line contours, use 
    /show,x11,,1
