Hi,
<div><br>
</div>
<div>Are you using the confine option? The message is telling you that after trying 100,000 times, it still has not generated a particle that is within the both the confinement volume and the source volume. The message explains that this happens if your confinement
volume is too small with respect to your source (or if you did not overlap the confinement volume or if you forgot to add a confinement volume).</div>
<div><br>
</div>
<div>The confine option is definitely not very efficient. I would recommend trying to get the same results you're trying to achieve without the use of confinement.</div>
