Question:

Is it possible to define different stiffnesses for tension and compression between two surfaces in the diagram of a line release?



Answer:

It is possible to define different properties in the tension and compression area of a line release as shown in Figure 01.



However, when releasing lines between two surfaces, there is a special feature regarding the released surface. In the attached model, an identical line release is defined. The bottom surface 1 is released for the left model, but the top surface 4 for the right model. For both surfaces, the local y-axis of the surface is aligned parallel to the global Z-axis.



The deformation diagram results in completely different deformations for both models.



In the left model with the bottom released surface, the pressed area is very soft. For this axis orientation, the reaction force of surface 2, which presses surface 1 from above, is very soft.



In the model on the right, the upper surface is released, so that the reaction force of surface 4, which presses surface 3 from above, is very stiff.
