Modelling surface contact forces

How can I model the surface contact forces for the exoskeleton design. Can anybody give me an example or a tutorial please…? It would be really helpful for me.

Hello Isuru Kumarage,

At the moment this is possible using conditional contacts which you can read more about on the Wiki 1, 2 and older forum posts. Another example of this is the SeatedHuman model in the AMMR examples, where the same concept are used between the subject and the seat.

Another possibility is using FDK which is a bit more complicated. The idea is that you can use “springs” to represent the fixation between the two surfaces together with surface contact force. This tutorial explains it well.
