WRF crashing after running a while

[Parvathy]

Hi, I am trying to run some simulations in WRF and for one set, it ran successfully and i was able to get the output without any issues. I am running a two way nested 3 domains of resolution 18km, 6km and 2km respectively. After running one simulation, i changed the physics parameters and tried to run the model but it keeps on getting crashed after a few hours. It showed a segmentation fault just like Felipe_SM (@Felipe_SM ) but the signal is shown 11. I saw another forum which said about the segmentation fault (signal 11) error but the exit code is also different for this query and so i am posting this as a new thread.

I ran the model initially at 64 cores and it ran for one set of parameters while for the second set 64 core run is crashing. i tried changing the physics parameters into others but despite the time at which the simulation is crashing varies, the simulation doesn't run fully. I will attach the namelist.input and namelist.wps and the terminals screenshots for reference. Regarding the issue with space, when i ran the simulation, after that i transferred the data and now around 235GB is available. the previous run made files of around 54 GB and i transferred them. So there is enough space for the simulation to run, I guess. And so i am not ableto understand the reason as to why this is happening. Can someone please help with this issue?

In your namelist.input, please set

dx = 18000, 6000, 2000,
dy = 18000, 6000, 2000,
time_step = 60
w_damping = 1
epssm = 0.5
gwd_opt = 1, 1, 0,

Then try again. Let me know whether it works.

Thank you sir! it worked.

Thanks for the update, --- I am glad it works!
