[kslim]

Hello Every body,
I hope all is well.
I have a problem with MCNP6 code for using burn card, so please can anybody help me ?

particle maximum smallest largest always always
cutoff particle table table use table use model
particle type energy energy maximum maximum below above
1 n neutron 0.0000E+00 1.0000E+36 2.0000E+01 1.5000E+02 0.0000E+00 1.0000E+36

fatal error. Models required. Cannot use memory reduction option.

Make sure the units and magnitudes are correct.

What is 1.0000E+36? That seems like a large number.
