Question:
Is a load considered within the surface for "Nodal support with column"?
Answer:
The load within this area is not taken into account, which can be seen clearly in the example in Image 01. Here, a homogeneous temperature load (Tc only) was applied, which leads to stress peaks, although the surface can freely strain.
If it is important to consider the load, you can also model the support manually. To do this, simply create an opening of the size of the column and create a new surface corresponding to the surrounding surface (see Image 02). The values for the spring stiffnesses can be found in the dialog box (see Image 03).
A surface subjected to such a load is then also stress-free when subjected to a temperature load, as shown in Image 04.
