My first thought would be memory issues. Would you provide more information about your computing resources?</div>

For example, cluster computing, workstation, or personal laptop.</div>

Can you provide more information about your simulations? <span style="margin:0px; font-size:12pt"> Are you using an analytical or voxelized water phantom?</span><br>

<div dir="auto">Hello everyone
<div dir="auto"><br>
</div>
<div dir="auto">I m asking for help, I m a beginner in using Gate and use it right now to simulate pdd and profils of photon beams in radiotherapy, the problem I had is in the definition of the number of primaries, every time I want make it bigger the simulation
crashes, right now I couldn't exceed 2 billion particle and once I try to use a bigger number it crashes without knowing the causes.</div>
<div dir="auto">I ll be grateful if I receive advice from you to remedy this problem </div>
