Created attachment 544 [details] /gps/source/list error Hello All, I believe I have found a bug in Geant 4. My source definition is below: /gps/particle neutron /gps/pos/radius 0.5 cm /gps/pos/centre 0.704 0. 1. cm /gps/pos/type Beam /gps/pos/shape Circle /gps/ang/type beam2d /gps/ene/mono 0.025 eV However, whenever I do /gps/source/list, it shows me the wrong value as 1MeV which is default. To prove it I did /tracking/verbose 1 and saw that the transport is for the correct value of the source. I have attached a screenshot as a proof. Thanks very much! Regards, Sanchit Sharma
Comment on attachment 544 [details] /gps/source/list error I am having this problem for a long time.
Hello. I'm sorry for taking so long to respond. This is a known issue of primary generator classes (both particle gun and general particle source) that are used in the multithreaded mode. Given primary generator is thread-local, all UI commands for primary generator are broadcasted all together to worker threads at the beginning of event loop. While /gps/source/list command displays the "current" value before the beginning of the event loop. This is the reason why you see the default values. We cannot broadcast each individual command to worker threads during the Idle state. Thus, even though the printout is not instantly updated, commands are actually sent to worker threads. We understand your inconvenience. But, in addition to the incorrect printout during the Idle state, could you please check that the correct printout from each worker thread? Makoto
Respected Dr. Asai, When I check my emerging particle energy with "/tracking/verbose 1", It shows me the correct value. Thanks!
Thanks for confirming it. Makoto
