How to eliminate tension from a subsoil?

When using the functionality subsoil you can input subsoils on your 2D-elements. But these subsoils have by default tension capabilities and therefore the subsoil can get under tension which is not realistic. Negative contact stresses are tension stresses in the subsoil.

In order to eliminate these tension stresses in the subsoil you will need to activate the functionality ‘Support nonlinearity/Soil spring’.

Next you will need to create nonlinear combinations in order to be able to execute a nonlinear calculation. Tension will then be eliminated for the results of the nonlinear calculation.
