Consider a single linear element (linear elastic material) whose end points are constrained by Spring Foundation nodes with some finite spring constant (say 1 N/m). Let's say my nodes are at 0,0 and 0,-1 and this is a 2D simulation. Now I apply Point Load (say 10 N) to the 0,-1 node, for example in the -y direction. Since my example lacks fixed constraints, there is simply nothing to prevent nodes from shifting when force is applied. Once the Point Load is balanced by the spring restoring forces and the tension in the elastic element then we reach a stationary solution. So now I want to do a Stationary study and find out how much the nodes shifted. Seems simple. I go to Results, Point Evaluation, use my Soluton data set, select the two nodes and ask for the y coordinate. When I go to Evaluate this, I get that the nodes are at 0,0 and 0,-1 or in other words they did not shift at all. This makes no physical sense so I am doing something wrong. I hope someone here can point me in the right direction.
