<p class="MsoNormal">Hello all,<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">I am trying to use a Fluence Actor but running into a problem. To make sure that my macro is working, I made a very simple case of 5 box shaped water volumes each 1mm thick in a stack. I placed a 511 keV gamma point source 100 mm away from
the stack and set the world material to vacuum.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">The problem is that only the nearest water volume is recording fluence data. I get output files for each of the other ones, but they are all recording zero. I expect each slice of water to record a number of gammas entering it.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">Is there any special trick to using the Fluence Actor?<u></u><u></u></p>
