While it&39;s quite a short period, I&39;ve experienced the mess with WRF so many times, and I think it&39;s time to recap those issues, not just for assisting my own future research, but for others who are studying in the same field. At present, we don&x27;t use this option. Hi Mauro, This is actually a bug that I&x27;ve noticed has caused issues for other users on the forums, and one that I&x27;ve spent a fair amount of time looking into. Causes Model becomes unstable, mostly because the time-step used is too large for stable solution, especially while using high-res simulation grids. Photo by Chris Welch The Verge. To check if the diurnal cycle application was successful, run the following python script, which should be within WRFUoMEMIT, and is automatically linked to your run folder during pre. WRF-SFIRE simulations sometimes crash because of a too large time step. > Blow > ups (CFL violations due to big values of W) in low levels at a single > steep slope point in the domain, within 2 min of integration.
