Hi Patrick, So these diagnostics fields are output as all zeros when using DIVA: Um_Dissi Um_Advec Um_Corio Um_AdvRe Um_AdvZ3 ADVx_Umo ADVx_Umo ADVy_Umo ADVrE_Um VISCy_Um VISCx_Um VISrE_Um PHIHYD and i think density diagnostics too....but haven't checked yet. Any chance at getting any of them back? -Matt
