How to add vibration

Hi Zhong,

This is muscle wrapping issue, the modifications you did to the drivers etc. seems to make it run ok, but the muscle path could not be determined correctly for this muscle.

If you have access to the newest AMS version 7.3 the cure is simple since it has a new muscle wrapping algorithm which is both much faster and more reliable. It can be enabled using this statement in your main file.

Main ={
System.Compatibility.AnyBody73_ExperimentalShortestPathSolver = On;
};

Note also that this requires AMMR 2.3, since modifications has been made to several muscles.
See this message for more details

Best regards

Alternatively the simplest thing to try is to increase the variable "StringMesh" in the muscle, this may help the muscle to converge.

Please also see this section of the wiki which describes solutions for this.
