Hello,
I am having difficulties with getting wrf.exe to run for more than about 1-1.5 hr. At that point it always fails with the message
Often, I will also get the following message, with the model failing with the segmentation fault occurring shortly thereafter.
I've gone through a number of forum pages and tried suggestions given to other users, but I continue to get the same result. I was hoping that someone may have some advice on other things I could try.
I am using NARR forcing data with grid resolutions of 9, 3, 1, and 1 km, and there are two innermost domains. I have attached my most recent namelist.input and rsl.error files. The namelist.input settings that I have tried and their results are in the table below. The "fail time" column indicates the model time where it failed, with the longest being able to simulate up to ~45 minutes. Based on my smallest domain and results from the number_of_procs.py file, the highest number of processors I can use 120 (3 nodes, 40 cores each). Any help would be much appreciated.
