Numerical Solution

Before we get ANSYS Mechanical to In the solve step, ANSYS will solve our boundary value problem , we have to tell it 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. In the solve step, ANSYS will obtain the temperature distribution in each element and from that populate the result items requestedANSYS 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 the result requests before hitting Solve.

Temperature

To obtain the temperature distribution in the domain, (Right Click) Solution > Insert > Thermal > Temperature, as shown below.

(Click) Solve, . ANSYS will:

• obtain 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
