I'm running a CESM simulation with CO2 at 185 ppm CO2. I'm using CESM1.2.1 with CAM5 FV 2deg and POP2 1deg.The simulation was started from an equilibrated ocean and has been running without problems for 5 centuries now. The climate over these 5 centuries is colder and equilibrated.However, on year 506 I get the following error:ERROR: ice remap transport: monotonicity errorWhat is the best way to diagnose what is going on?
