<p class="MsoNormal">Hello GATE users,<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">I am running into a segmentation violation error that seems to depend on material selection. I am simulating tubing with Y-90 in it. For some tubing materials, I get the following seg fault. If I make the tubing from Water, though, I get
no error.<u></u><u></u></p>
<p class="MsoNormal">The virtual machine I’m using has multiple CPUs. It seems that I get no error if I run the same script on a VM with only one CPU.
<u></u><u></u></p>
<p class="MsoNormal">The error seems to be while GATE is shutting down, so it doesn’t appear to affect my simulation results.<u></u><u></u></p>
<p class="MsoNormal">I’ve run this type of simulation many times, so I have no idea what might have changed. Any ideas?<u></u><u></u></p>
