<p>Dear Gate users,</p>
<p>I'm am trying to create a phase space at the exit of the treatment head of a TrueBeam for Stereotatic Radiotherapy. The simulation uses generic moves to have an arc of 180° around a phantom (magenta cube).</p>
<p>The simulation aims to sotre an phase space (in the red plane) using PhaseSpaceActor for the entire arc. The source is also a phase space attached to blue plan.</p>
<p>The simulation always crashes with break segmentation fault.</p>
<p>Below, a visualization, and some error messages. I also attached the simplified macros (make_out_phsp.tar) used with a 1000 particle test phsp as input.</p>
<p>I tried unsuccessfully to :</p>
<p> - use gps</p>
<p> - change the phase space source</p>
<p> - modify my phase space actor options</p>
<p> - convert each rotation and translation of each step with a static position</p>
<p> - Gate v7.2, v8.1, v8.2</p>
<p>The problem is the same.</p>
<p>But the same simulation with a different actor (DoseActor) do not fail.</p>
<p>I must be doing something wrong...</p>
<p>Thanks a lot for your help,</p>
<p> </p>
<p>Best regards,</p>
<p>Jeremy Leste</p>
