Rib Intrusion
Fig. 6: Nodes for extracting Rib intrusions
The rib intrusions can be measured by determining the distance between nodes. The nodes shown in Fig.6 are coincident at the beginning of the simulation. An increase in the distance between the nodes gives the rib intrusion of the model.

Alternatively, the elongation of a spring can be used to determine the rib intrusion. The spring elements are listed in the table below. The springs are located in the piston bearing system.
We do recommend to use spring elements to determine the Rib intrusion.
