Dear Zhefu Lee,

1. You have an error in your geometry definition (BLKBODY region).

must be

2. Delete EMF and PHOTONUC cards.

3. Are you sure that the refraction coefficient of the GLASS material
equals 1? I don't thick you will get any results with such value.

4. Try increase threshold for electrons in case of very long simulation

Best regards
