<div dir="ltr"><div><div><div>Hi all WRF Users,<br><br></div>1. I had a similar problem, I have adjusted the Model to 18km, and have also tried to increase the met_grid or e-vert from 27 to more levels, however, when I run the model it gives me an error that the input file has only 27 levels.<br>
<br></div><div>2. The model became unstable at certain times and at times it dumped the core. I have resolved this by reducing the time_step, however, am wondering why this happens?<br></div><div><br></div>Any idea how these can be resolved? Am all ears.<br>
