Segmentation fault with I4DVAR

I am getting this error right at the first time step of a I4DVAR run. This is the first time I have run this case with version 930M. I am attaching my log, and .in files. I was thinking this might be a memory issue so I am specifying "ulimit -s unlimited" in my .bashrc file. Any help would...

ad_LBC with npzd_Powell

I am running an IS4DVAR case with the NPZD_POWELL model. I am getting a formatting issue with the ad_LBC. Here is the output from my log file. The NO3 state variable is not getting the correct ad_LBC. I am guessing it is a just a simple formatting issue with my npzd_Powell.in file. Any help will be ...

Re: Cauchy-Poisson wave patterns in velocity increment W4DVA

So I think my problem was that I had the number of iterations in the biconjugate gradient algorithm used to solve the elliptic equation for the balance operator set too low for my domain. Initially I was using Nico = 200 but now I have it set as Nico = 3000. This causes my problem to disappear. I ha...

Cauchy-Poisson wave patterns in velocity increment W4DVAR

ROMS Post I am running the W4DVAR with strong constraint (NADJ=NTIMES) on an 800m resolution grid (40 vertical levels) with initial and boundary conditions taken from 3.7km regional NCOM (USEAST). The surface forcings are taken from a WRF model that is NOT coupled to the ROMS model. I am assimilatin...
