Fail to run Vortex following option

[Khin Myat]

Hi WRF community members,

I am trying to run a simulation with automatic vortex following option. When I add and run the simulation with the following namelist variables,
corral_dist = 8,8,
track_level = 50000.,
time_to_move(max_dom) = 0.,0., , the simulation can not be run.
If I do not add those variables , the simulation can run successfully. I also got the ATCF data in rslout file and the simulation could be run successfully.
My question is , do we have to add those variables in namelist to run vortex following option? if the simulation can run successfully without those namelist variables, can we say is that simulation successful?
What should I check to fix the problem?
I also attached the namelist and track results.
Can we run the static nesting simulation with the results of vortex following option (i.e wrfout file of vortex following option)?
Thank you very much in advance for your time.
Best ,
Khin

It is better you set these options based on your case. However, if you don't set these options, the default values will be used.

And yes, if the case was done successfully, we take it as a successful run.

What should I check to fix the problem?

You can run a static nesting case, i.e., don'r compile WRF with the vortex-following option. Instead, you design nested model domains, and the storm is contained within the child domain.

Thank you very much in advance for your time.

Sharing my relevant settings with you may help you:

time_to_move = 99999999,0,0,
vortex_interval = 15,15,15,
max_vortex_speed = 30,30,30,
corral_dist = 8,8,124,

In my opinion, the outermost domain should remain fixed

@Hans
That is correct. Even with vortex-following option, the outermost domain should remain unchanged.
