Numerical Solution

In the solve step, ANSYS will solve our boundary value problem numerically and obtain the temperature at each node. It is important to keep in mind that all other results are derived from the nodal temperatures through interpolation.

Before we hit Solve, we can tell ANSYS what results we would like to look at. ANSYS will extract these results from the nodal temperatures and report them. We could alternatively add in these results after we obtain the numerical solution. Below, we do the former and add in some result requests before hitting Solve.

Obtain the Numerical Solution

(Click) Solve, Image Removed. ANSYS will:

• calculate the element stiffness 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
