Varying deltaInt parameter¶
This is still a work in progress. I'm attaching some preliminary plots only; documentation will be completed later.
Studying error and simulation time in terms of deltaInt (without crossing planes)¶
- Without crossing planes, we expected beforehand no significative changes in the errors nor the simulation times.
- This plot validates this intuition.
- Note: as
G4_max_x_errremains essentially constant, its curves are collapsed in a single one (which appears between 1 and 0.1 mm in the leftyaxis).
Studying error and simulation time in terms of deltaInt (with crossing planes)¶
- This is a continuation of the previous experiment that instead uses a non-zero number of crossing planes.
- As expected, simulation times not only grow with the number of planes but also with lower
deltaIntvalues (this was already discussed and is consistent with the plots of the next section). G4_max_x_errdoes not change in any of these scenarios.
Studying simulation time in terms of deltaInt (with crossing planes)¶
- This plot shows simulation times for six values of
deltaInt(between 1e-10 and 1e-5) and an increasing number of planes. - It was expected to see differences in the curves, as
deltaIntcontrols how accurate should be the detection of the intersection points. - In every case, the times grow linearly with the number of planes. The lower
deltaInt, the higher the slope of the line, which is reasonable.
Studying error when detecting crossing planes¶
- This is related to this experiment.
- In this case, when
deltaInt= 1e-7, the accuracy improves very subtly, but remains constant afterwards. That is, fordeltaIntin [1e-10,...,1e-7], the intersection points found by Geant4 are exactly the same.
