G4PhantomParameterisation::GetReplicaNo()

[lmqmeiqi]

I want to use G4PhantomParameterisation build a phantom(Geant4.11.0), and encounter the following problem:

When I run the same code in Geant4.10.06, I get the following prompt:

Why does this happen, and how can I solve it?

It is probably a precision problem, please see DICOM example Stuck Track error for small voxels

Thanks for your reply！I tried but there was a problem.

There is something wrong with this sentence…Maybe there should be an operator, right?

Of course, you have to put
100kCarTolerancestd::pow(10.,fNumberOfZeroSteps)

[mkelsey]

And you need to use the backquote (accent grave) to delimit code; otherwise the multiplication (asterisk) gets interpreted by the forum as “make this italics.” The full expression should be

Step += 100 * kCarTolerance * std::pow(10.,fNumberOfZeroSteps);

Thanks Michael, I did not realize of it
