Maximum barotropic Courant Number = -1.00000000E+20
Maximum Coriolis Courant Number = -1.00000000E+20
1.00000000E+20 - there is abnormally large number
output data of temperature, salinity and u,v-components are 1e+37
what is the reason?

Re: big barotropic Courant Number
Is this for the initial conditions? There's something wrong and you will have to investigate it further. Where do the initial conditions come from? File or ana? If a file, have you looked at it with ncview? Are the fields in bounds there?pavel_fayman wrote: output data of temperature, salinity and u,v-components are 1e+37

Re: big barotropic Courant Number
no problem with initial and boundary conditions - all ini and bound data take from netcdf files
