Question trouble with G4Cerenkov after upgrade to 4.9.5.p01 

Forum: Processes Involving Optical Photons

Hi All,

I have a code that works with geant4.9.3.p01. Decided to try it with geant4.9.5.p01.

I noticed that no optical photons are being produced with new version.

i was registering the Cerenkov process as follows:

      if(fCerenkovProcess->IsApplicable(*particle))
	{
	   pManager->AddProcess(fCerenkovProcess);
	   pManager->SetProcessOrdering(fCerenkovProcess,idxPostStep);
	}

-----------------------//

The application developers guide suggests to register Cerenkov process as continuos so I switched to:

      if(fCerenkovProcess->IsApplicable(*particle))
	{
          pManager->AddContinuousProcess(fCerenkovProcess);
	}

but now I get message:

  G4ParticleChange::CheckIt    : the local time goes back  !!
  Difference:  0.0045479[ns] 
  G4ParticleChange::CheckIt    : the proper time goes back  !!
  Difference:  0.00309127[ns]

any ideas to what might be causing this?

thanks in advance,

Aram
