ERROR NAN

Good afternoon, I am making a naysCube model of an estuary, for which I am using “Movable bed”, “2nd order non-linear k-e model”, “TVD MUSCL”, a constant flow of 0.3 m3/s, “changeable wet and dry cells” -> 0.01 (m), roughness 0.1 (manning), grain size 0.019 (m) and the rest by default. I would like to model 3600 sec, “start time of bed move” ->300 sec, but I have tried with Variable DT whit CFL contidition Variable DT and Fixed DT, and it produces an error, which I attached, I don’t know why, my mesh is 10 cm.

On the other hand I have doubts with the data while processing, because several of these I do not know what they mean as the following:
KT= 320130 T= 320.128999999756 SLOPE=1/ 55.7742877510784
SI_now= 1.792940869927406E-002
