Driver Resulting in Solver Failure
Hello,
Earlier I posted a question about the solver failing due to custom inertia values. Now that thing is sorted out, but the new thing is I am modeling with a detailed rider now, the solver is failing and sometimes not solving at all without error, so when I deactivate the driver, the solver works fine and when I activate it gives an error. I tried to simplify my model by adding a simple rider instead of the detailed one, but the error is still there. the error I get is the menitoned below. I have not edited the driver and have taken the default values for mass and inertia.
