Dear FLUKA experts,
The attachment is my file.There is no response when I run the file(no error or progress),could you help me to find the reason?

Dear @xiongbp,
Your input has errors in geometry. If you look in the flair “geometry tab” you will immediately see the “Error found” message. The second zone of your VOID region overlaps with the CORE region.
