Hi Jeff,
If you want results at the nodes, do not use the "Ribbon > Probes" command. Use the "Model Tree > Nodes > Query Display" command instead.
The Ribbon > Probes interpolates the result on the surface based on the position of the mouse. (This is why it lists the element number; that shows which element is being interpolated.) The Nodes > Query command will snap to a node (so the result is repeatable) and gives the node number.
Also, I sometime use "Model Tree > Elements > Query Display" because this shows the result on all the nodes on the element. Of course, you need to know which of the N nodes correspond to which of the corners.
