FATAL CALLED: STOP: activate before 48000

Hi,
I got the FATAL CALLED which stop the simulation after 1 hour of run. I have attached the rsl files and namelist.input.

Can anyone please help me to solve this issue.

The FATAL CALLED is as follows.

-------------- FATAL CALLED ---------------
FATAL CALLED FROM FILE: <stdin> LINE: 2232
STOP: activate before 48000

Thank you so much in advance.

Hi Pramod,

The problem is that you have cfl errors:

This is likely caused by strong vertical winds coupled with too long of a timestep - Since so many points are having errors, the first thing to do is decrease your timestep (e.g., 4 * dx). If you still have issues, you may try a different PBL scheme, or try using the dynamics namelist options w_damping or diff_6th_opt.

Hi Jordan,
Changing timestep to 40s worked for me.

Thank you so much.
