Hi,
which is the proper way top run DIRC geometry?
I am using the old good standard:

  PndDrc *Drc = new PndDrc("DIRC", kTRUE);
  Drc->SetRunCherenkov(kFALSE); // for fast sim Cherenkov -> kFALSE
  fRun->AddModule(Drc);



But it is not working, it produces the following messages:

=======  DRC::  ConstructOpticalGeometry()  ======== 
Warning in <TGeant3TGeo::DefineOpSurface>: Called for surface MirrSurface. Not applicable in Geant3 - setting is ignored.
Warning in <TGeant3TGeo::SetBorderSurface>: Called for border surface BarMirrSurface. Not applicable in Geant3 - setting is ignored.

but in the TGeoManager I can see there is no DIRC!!
Which is the correct way to call it? I do not need the cherenkov propagation, the fast option is what I need top use.

Many thanks in advance.

The proper way to run DIRC geometry is the following:

Drc->SetRunCherenkov(kTRUE);
Drc->SetGeometryFileName("dirc_l0_p0.root");
fRun->AddModule(Drc);

(see trunk/macro/drc/sim_dirc.C)


And those warnings when you run the DIRC simulation with geant3 are harmloss, in geant4 they disappear.

Hope this helps.

Ehm,
when was it changed exactly? I do not remember any announcement.
Just to understand since when we have no DIRC in simulation.

The Barrel DIRC geometry is in the .root file in trunk/geometry/dirc_l0_p0.root since 2 weeks.

I did not do any announcements except of comments when committing the changes to the svn. Should I have created a topic in the forum too?

In theory an announcement could be good Smile
However, now that I know it, I will update the "default" macros according to.
Thanks for the fast reply.

I'll inform the PANDARoot-ers the next time.

Sorry for misleading.

To run the DIRC now you need an updated trunk/drc, trunk/geometry and trunk/macro/drc directories.

Best regards,
Maria

Is it possible to set Cherenkov kFALSE, in order to not have the full cherenkov propagation and to be faster?

I think so, if you don't want to have any photons.
I've never tried though.
