Simple geometry was made having concentric cylinders bounded by a square region. The geometry has a reflective boundary. The source was defined at one point in the boundary and when it had been run for criticality calculation, it resulted in an error messaging "the entire source was rejected". I tried to do the simulation by placing the source closer but it still results in an error. Any help will be appreciated.
Norbert Hugger Hi! Thank you for the response. I didn't use SDEF card. I am attaching my script below.

I see some issues with how your geometry is defined. Cells 101, 201, 301 and 401 are infinite and should be bounded by a pz surface. Cells 501 and 601 should have 6 surfaces if it is meant to be a box.
When using a kcode/ksrc card, the geometry is sampled before running the simulation. The issue is likely with the source trying to sample an invalid geometry.
