Segmentation Fault in WRFDA

Post by danny7kd » Thu Jan 03, 2019 8:28 pm

Hi all,

Finally got WRFDA to run, but now I"m getting a segmentation fault (rsl.error.0000) attached. I don't see an obvious time step change I could make, is there something else that might help?

Thanks!

Dan

Problem fixed. time_step in the namelist file was set to 360. I needed to cut it to 10 (might have been overkill, but that solved the problem, will try nudging it upwards).

Hi Dan,

I also got a segmentation fault error when running WRFDA 4DVar. Followed the user guide and tutorial, I used the test data downloaded from https://www2.mmm.ucar.edu/wrf/users/wrf ... tdata.html. My rsl.error.0000 and namelist.input are attached below. My WRF and WRFDA version are all V4.0. I have tried adjust time step, but no effect, is there something else that might help?

Thanks!

Zhang
