Hi! I’m trying to modifying geometry with UI commands in Geant4 example extended/analysis/AnaEx01. After compiling, I just simply typed ./AnaEx01 and opened a openGL GUI window. And then:
/det/setAbsThick 20 mm
/run/beamOn 1
Then the GUI window crashed, with these outputs:
/det/setAbsThick 20 mm
/run/reinitializeGeometry
/vis/scene/notifyHandlers scene-0
/run/beamOn 1
Start re-initialization because
Geometry
has been modified since last Run.
userDetector->Construct() start.

Obsolete world logical volume is removed from the default region.
