Click on the Forum title, e.g. on the "Forums by Category" page, to read a sequence of postings to the Forum and its threads all in one page. If you are only interested in one thread or the thread following a specific posting, click the thread or the posting, which takes you to a smaller page, which contains only the part you are interested in and may be easier to navigate.
Messages are "chained" if there are only replies at the first level, i.e. 1/1.html, 1/1/1.html etc. In case of "chained" messages the message number is replaced by the icon and there is no indentation.

I defined a region with cuts in Geant4 10-04-patch-02, used in multi-threading mode. The cuts are applied in DetectorConstruction.cc, where the G4Region is defined as well. I am using G4MTRunManager.
When I run my code I get
-------- WWWW ------- G4Exception-START -------- WWWW ------- *** G4Exception : GeomMgt1001 issued by : G4Region::G4Region() The region has NOT been registered ! Region detRegion already existing in store ! *** This is just a warning message. *** -------- WWWW -------- G4Exception-END --------- WWWW -------
for every thread except one. I understand it is because every thread tries to create a region, but only the first one succeeds, since the region itself is a shared resource.
My question is: how can I solve this? Can I force the creation of the region in the master thread only?
Thank you for your help.
