[Gate-users] NbOfHits

[Eric Moszczynski]

Hi gate users,

I am using DoseActor and I use to enable the NumberOfHits. My problem is the following : I observed a increase of the number of hit when a interface between two volumes is met. It as an impact on the dose values.

In my case, i have a volume of Air and a volume of water, my volumes are separated with empty space(vaccum) but I have still this issue.


The NbOfHits file is returning something like this :

Air-NbOfHits.txt
