Elastic Nodal Support 1
Tips & Tricks
Often, it happens that stress peaks occur on a nodal support that is attached to a surface. It is possible to avoid such singularities by modeling the nodal support as a column.
To access the ‘Edit Column’ dialog box, open the ‘Edit Nodal Support’ dialog box where you click the button for ‘Elastic Support via Column in Z...’. In the left picture, the nodal support (point support) is replaced by an elastic node support which softens the singularity. Furthermore, you can choose the modeling as ‘elastic surface foundation’ and as ‘node support with adapted FE mesh’. The support conditions on the head and base of the column can be set as well.
