space-time extreme gridded output

[adefaizal]

Hi

I would like to ask about the space-time extreme grid output of WW3. In some cases, I found a strange value of STMAXE (-158030) and a negative value of HMAXE with a normal result in significant wave height. I have followed the CFL conditions. I wonder if there are any additional conditions that need to be satisfied to define the space-time volume (STDX, STDY, and STDT) before running the simulation.
