simulation of soft robotic actuator

Please login with a confirmed email address before reporting spam

Hey everyone,

I am simulating a soft robotic linear actuator in COMSOL Multiphysics. The actuator is compression based so I apply a negative pressure on the internal surfaces. I need to set up the simulation in such a way that it recognizses when the part comes in contact with itself. For this I have provided contacts. But when I provide contacts the solution does not converge at all. I am using a hyperelastic material model for modelling. I have also tried to use Nitsche contact method for self contacting but the same issue persists. Can anyone please help me with it! Thanks!!!
