  1. Yes, the instability occurs around the z_sh modification. However it is a direct rainfall model and the rainfall does not start until the 5minute mark. The model generates a massive amount of water on the first minute. Its puzzling me.
  2. Hi all, I am running a direct rainfall model and I am getting an instability right at the start of the run, before the rainfall actually starts. It only appears when I add some Z_SH layers to my TGC file. Can anyone help me figure out how to stop this as it really affects my results? I have a 2m grid and normally run on a 1 sec timestep but I have to drop it to 0.25 sec to get it running then the surge is introduced. Please Help!
