Then click on OK to close out the box. Go back to the Preprocessor Menu and click on Mesh. Then click on OK in the Mesh Area dialog box. After a few moments, a mesh will appears in the graphics window. Pull down the menu labeled Plot by clicking on it.
Various choices appear for plotting.
To plot all the entities, click on Multi-plots at the end of the list. Now you are ready to apply the loads to the model. Note that the default loading on each surface node is an insulated boundary. So, along the outside vertical lines of the model, there is no need to specify explicitly the insulated boundary condition since it is already present. Next, you will want to place the temperature loading on nodes, so click on On Nodes for this choice.
