# Changing max step size affects angular velocity [closed]

Hi,

I was recently graphing the relative angular velocity of a link(applying torque via ROS' Wrench service) and decided to change the "max step size" in Gazebo GUI parameters from 0.0001 to 0.0000001. When I did that, the magnitude of the angular velocities decrease by a factor of ~4 for some reason.

Why does changing the "max step size" change the angular velocities so drastically? Should I be expecting such a drastic change in the system? Intuitively, I would've guess that decreasing the "max step size" would decrease the uncertainty not the magnitude of angular velocity.

This is really a question about the mechanisms underlying Gazebo's dynamics simulation. I think you'll have a better chance of getting good answers over at answers.gazebosim.org. As such, I'm going to close this question.
Having said that, could I ask you to post a link to the question you open at answers.gazebosim.org so future readers have a way to get to a (potential) answer?
