I'm trying to sumulate a wheel (e.g. a car's tire)rolling over a road in a non linear study.
I put a "bearing load" (I have the sofware in spanish, I don't know if this is the name used in english version)in the axle of the wheel, and I'm using a "reference geometry" to restrain movement to rotatate 0.2 radians, 0 axial traslation, and not restrained vertical/horizontal translation.
Contact restrain between the wheel and the ground is "no penetration" with a friction coefficient of 0.13.
The problem is that the tire rotates but, doesn't "roll" over the ground, it doesn´t move forward, seems like it is slipping in the same place.
I suppose that since the contact is no penetration with friction the wheel must roll forward.
Any input will be appreciated.
