Dear all,

I've noticed that the DIRC is missing in my simulation; in fact there is an error message. I load the following in the macro:

  PndDrc *Drc = new PndDrc("DIRC", kFALSE);
  Drc->SetRunCherenkov(kFALSE);
  fRun->AddModule(Drc);


Then, ROOT tells me:

======= DRC:: ConstructGeometry() ========
=============================================
Geometry format not supported!
=============================================
Warning in <TGeoVolume::AddNode>: Volume cave : added node DskBase_1 with same name


and the "usual" warnings from ConstructOpticalGeometry()


Anybody has a comment to this?

Cheers
Olaf.

You are using an old macro. Check new macro/pid/run_sim_xxx.C

My macro is new, just the DRC part was old Wink
However it's a bit annoying that for each detector I have look through all the corresponding macros to find a recent and complete version ...

The standard macros are in macro/pid since years Smile

Please add the following line to the macro:

Drc->SetGeometryFileName("dirc_l0_p0_updated.root");

this geometry file is in geometry/ directory.

Hi Maria,

I just realized that with

Drc->SetGeometryFileName("dirc_l0_p0_updated.root"); 


I cannot build the geometry with Geant4 (jan12):

Quote:


===> GEANT4 materials created and mapped to TGeo ones...

-------- EEEE ------- G4Exception-START -------- EEEE -------
*** G4Exception : G4Root_F003
issued by : TG4RootDetectorConstruction::CreateG4LogicalVolume
Cannot make material for volume: BarrelDIRC

*** Fatal Exception *** core dump ***
-------- EEEE -------- G4Exception-END --------- EEEE -------

*** G4Exception: Aborting execution ***



Do you now what's the problem here? I updated already the DRC and geometry directory.

Cheers
Olaf.

Dear Olaf,

actually I did not come across such problem.

if it is possible, I'll try to solve it as soon as I'm back at GSI in the middle of March?
If you need it right now, I'll try to fix it right now.

Maria

please make sure you've changed the g4config.C as in mine (/u/mpatsyuk/PANDA/trunk/gconfig/g4Config.C)

helped to cure the error before, but now I encounter the next one:

Converting Root geometry to Geant4 via VGM ... 
/misc/cbmsoft/Lenny64/jan12/fairsoft/bin/root.exe: symbol lookup error: /misc/cbmsoft/Lenny64/jan12/fairsoft/lib/libRootGM.so: undefined symbol: _ZN6RootGM14DisplacedSolidC1EP8TGeoBBox


This looks like an internal problem in Root?

Olaf.

yes, this problem looks new to me.
Actually we have also other unsolved problems (caused by root) with jan12 packages so I would recommend you to use the older ones to run the DIRC simulation.

Hi Olaf,

could you please try again at GSI Lenny64. I found out that we missed to compile some new files. I fixed it now for the following SIMPATH /misc/cbmsoft/Lenny64/jan12/fairsoft/

Now it should work.

Ciao

Florian

Hi Florian,

I just tried it, and the previous reported error is gone. However it still does not work:

Quote:

Converting Root geometry to Geant4 via VGM ...

-------- EEEE ------- G4Exception-START -------- EEEE -------
*** G4Exception : GeomSolids0002
issued by : G4Polycone::G4Polycone()
Cannot create a Polycone with no contiguous segments.
Segments are not contiguous !
rMin[3] = 45 -- rMax[4] = 31
rMin[4] = 30 -- rMax[3] = 46
*** Fatal Error In Argument *** core dump ***
-------- EEEE -------- G4Exception-END --------- EEEE -------


*** G4Exception: Aborting execution ***



Which looks again like a problem in the geometry.

Cheers
Olaf.

Hi Olaf,

I agree that the error looks more like a problem of the geometry. It looks like that the vgm conversion starts correctly. Since I don't know anything about the DIRC geometry I can not help here.

Ciao

Florian

Hi Olaf,

I could not reproduce your error

with Jan2012 packages.
Maybe we could meet to study the problem in more details or something like this, if this problem is still actual for you?

By the way, I don't know why you need the DIRC simulation for, we don't use the Jan2012 packages for the events simulation because the detector response is not quite ok with them.

Best regards,
Maria

Well, the DIRC is material budget, interacts with particles and produces secondaries. And we can use the fast mode to have smeared values for fast particle identification.
