Dear Nicolas,<br />
Thank you !<br />
My trouble is following.<br />
In my simulation,only when the [Particle Name] was neutron, the dose result was zero.<br />
All other particles were right.<br />
Even though in the whole target, the dose of filterable neutrons was still zero.<br />
I couldn't understand it.<br />
<br />
Regards,<br />
