At the first glance this looks like there is an inconsistancy between cross- sections and final state generators used in the LISA physics list. Can you find a physics list within the educated guess physics lists, that would fulfill your requirements? It should resolve the problem. With kind regards, Hans-Peter. |
Dear Sir, I am Timmy Francis, Project Associate in the Indian Moon Mission Program, Chandrayaan -1. My group is trying to simulate the lunar gamma ray back ground continuum in the Energy region of our interest (20-250 keV ), using Geant4.6.0. Our detector consists of a cylinder filled with material having average lunar composition. We are firing protons with a given input flux from random positions from a hemisphere such that protons are hitting uniformly on a 1 sq.cm area on the top face of the cylinder which is filled with the material having lunar composition. In the physics processes simulated, we have included hadronic processes also and since we found that the hadronic processes simulated in the LISA example which is given in geant4.6.2/examples, are satisfying our requirement we have simply copied that hadronic processes to our PhysicsList. But while the energy of the protons fired reaches about .460GeV, the program is aborting its execution, with the following lines: Event: 434272 In /root/geant4.6.0.p01/source/processes/hadronic/models/util/include/G4Fragment.hh, line 261: ===> G4Fragment::SetNumberOfCharged: Number of charged particles can't be greater than number of particles G4HadronicProcess failed in ApplyYourself call for - Particle energy[GeV] = 0.00613 - Material = Lsim - Particle type = pi+ *** G4Exception : 007 issued by : G4HadronicProcess GeneralPostStepDoIt failed. *** Fatal Exception *** core dump *** *** G4Exception: Aborting execution *** Aborted Sir, there is another problem which we are facing. Once we go to higer energies, (a few GeVs), the program is aborting many events reporting that the momentum direction was illegal. Sir, In our DetectorConstruction.cc, our fractional mass is not added up to 1, it is less than 1 by some .00000001. Could this be a reason for the above mentioned problems. Kindly send me a reply at your earliest convenience. Thanking You, Yours faithfully TIMMY FRANCIS. Project Associate, PLANEX Physical Research Laboratory India.
