h2. 5. Solution
Before we get ANSYS Mechanical to solve our boundary value problem, we have to tell it what results we would like to look at. In the solve step, ANSYS will obtain the temperature distribution in each element and from that populate the result items requested.
h4. Temperature
To obtain the temperature distribution in the domain, {color:#990099}{*}_(Right Click) Solution > Insert > Thermal > Temperature{_}{*}{color}, as shown below.

The default direction is set to x which suits us.This can be changed if necessary under the "Details of Directional Heat Flux" table.
h4. Obtain the Numerical Solution
{color:#990099}{*}_(Click) Solve{_}{*}{color}, !Solve_Button.png!. ANSYS will:
-obtain the element matrices
-assemble them into the global stiffness matrix
-invert the global stiffness matrix to obtain the temperature at the nodes
-populate the results requested from the nodal temperatures
