<div dir="ltr"><pre>Dear Gate users
Hello
I'm currently using Gate v7.1.
I tried to use setRmin for hollow sphere on nanometer scale.
e.g.,
/gate/sphere/geometry/setRmin 1 nm
/gate/sphere/geometry/setRmax 20 nm
However, I got G4Exception as below.
This error does not occur if I replace nm with mm OR if I use 0 nm for setRmin (=full sphere).
Could you provide any comments or help to solve this problem? I appreciate any help in advance.
