Hi,

Thanks for quick reply! I looked into the tracking/verbose 2 and it seems that when the neutron enters the material, it always makes inelastic scattering, producing secondaries, which are reflected backwards:

(Y=-50 is where my volume beginns!)

Is there a way to futher investigate what is wrong? Best regards, Sylvia
