Elastic Nodal Support 2

You can use the elastic support option to avoid singularities due to a fixed nodal support in RFEM. This can be defined directly in the dialog box of the nodal support as a column in Z. It is necessary to take into account the geometry of the column, the material, and the support conditions. Here, we want to look at the option of modeling the column as a surface foundation.

For the surface foundation, a surface with the column dimensions is detached, to which an elastic foundation is applied internally. The left plate is calculated with a support as a column, the right plate with a normal nodal support.
