Hi,

I am facing some problems while defining detectors for the forward part of the MVD. If I use a rectangular detector (see the screenshot from the eventdisplay that I am attaching) everything works fine, but if I introduce a trapezoidal detector (as the strips modules must be) the simulation is not storing any hit on this detector. I checked (see trapezoidal.png) and there are particles crossing my detector, however there are no MVD hits. I tryed with different distances from the center of the frame and the only thing making it work is to change the shape of the detector from a trapezoidal to a rectangular one. I also made a check with a circular detector and it is working. So the only shape showing problem seems to be the trapezoidal one.
I attach to this message the .root files with the two different geometry definitions and the macros which I used (runMvdSim.C and eventDisplay.C).
Does anybody have an idea about the reason of this behaviour?

Cheers,

Simone
