The fix we have found is to lag in the velocity in time from un/vn to ub/vb in the gathering of the surface velocities in icestp.F90 in the fields u_io/v_io. At nfice=1, this would make sense since this is the way one treats friction in leapfrog. For nfice>1, it also seems to help but then the logic is a bit lost on me...",Enhancement,closed,low,,LIM2,v2,,fixed,LIM* ice stress v2,
