Question Interaction length comparison 

Forum: Fast Simulation, Transportation & Others
Date: 07 Feb, 2014
From: George Dedes <George Dedes>


I put this question here, as it is generic and doesn't seem to fit anywhere else than a category that has "& Others":

For the decision of each step size, each process proposes a step and the lowest one decides the invoked interaction and the actual step size. I guess that each process returns either a macroscopic cross section or directly a mean free path, from which then a step length is sampled according to the exponential decay law. Then all step lengths should be compared and take the lowest. I would like to know in which class(es), the sampling and the comparison of the proposed steps is done.

Thanks in advance, George

PS: I see that printing the proposed step from G4Navigator::ComputeStep(), gives already the final proposed step, which coincides with the step length that I get from my SteppingAction
