Have you verified that your geometry is not overlapping?<br>

<p>Hi,</p>
<p>You would try to change production cuts to be a little bit bigger. <br>

<div>Hi,</div>

<div>I was simulating a X-ray imaging process with 2 x 10^9 events. It has been running over 5200 minutes and still ongoing. From the output I saw the following warning message about "Track stuck or not moving" as attached below (multiple times). However, when
I ran 2 x 10^7 events I did not have the same warming issue and the simulation was completed < 20 hours successfully. Should I worry about this warning or just ignore it and continue to wait? Thanks a lot!</div>
