Question G4PVReplica with G4Para or G4Trap 

Forum: Geometry

Dear All,
I try to build a 2D (XY) Cartesian array of parallelipipeds. The parallelipiped angles are (0, 30*deg, 90*deg). The thing is the geometry gets generated correctly (I can visualize it wiyth Open Inventor) but when I try to run the beam I receive the following error:


ERROR - G4SmartVoxelHeader::BuildReplicaVoxels()
        Replicated geometry, logical volume: logicalXReplica_name

*** G4Exception : FatalError
      issued by : G4SmartVoxelHeader::BuildReplicaVoxels
Sanity check: wrong solid extent.
*** Fatal Exception *** core dump ***

*** G4Exception: Aborting execution ***


In this case the replicated geometry logical volume name is logicalXReplica_name, but if I change the azimutahl angle from 90 to 0 the repported error volume is the mother volume to be divided.

So, the mother volume gets filled with replicas (there is no doubt about this) and the geometry is constructed corectly but the only case that works is when the polar angle is 0, i.e. when my paralelipiped is in fact a box.

Is this a bug or is just that the replication must be performed on surfaces perpendicular to the cartesian axes?

What should I do the replicate these parallelipipeds?

Thank you for you help.

PS. Originally I thought G4Trap was the problem but I get the same behavoior for trapezoids as well.
