Infinite tracking loop

Postby evgeny » Tue Dec 17, 2013 1:36 pm

Dear all,

my each second simulation aborts with the following message after some hundreds of cycles: "Fatal error in function Tracking: Infinite tracking loop".

I calculate one SFR assembly with 13 axial layers for few group cross section generetion of each layer. Axially the fuel pins filled from bottom to top with: helium + refl + fuel + helium + refl. I use reflective BC in radial direction and black BC in axial direction.

Does anyone know where the problem may be?

Best Regards,
Evgeny

This error message can be caused by a geometry error. Could you send me the input file by e-mail?
