Ocean Modeling Discussion

Thanks for the reply
I figured it out eventually. The shortwave radiation values generated from the forcingfile were way to high, and therefore the total energy became extremely negative after just one time step

Sorry for the disturbance

Hello, I'm having a difficult time trying to run the ROMS model on a local lake. The error states that the blow-up is because of the maxdensity, here 7.3*10⁵. How do I correct it? Below is some of the output from ROMS: Metrics information for Grid 01: =============================== Minimum X-grid s ...

I figured it out.
I had to change the h_min value in the grid-file from 0 meter to 1 meter (or another value unequal to 0).

Thanks

Hello I'm trying to model a local lake called Norsjø in ROMS. When running ROMS I stumble over an error which my colleagues and I find quite difficult. I represent the problem below: Program received signal SIGFPE: Floating-point exception - erroneous arithmetic operation. Backtrace for this error: ...

I can define another bottom variable, e.g UV_LOGDRAG instead of SSW_BBL, in other words # undef SSW_BBL # define UV_LOGDRAG But when I now run ROMS I got the error: Program received signal SIGFPE: Floating-point exception - erroneous arithmetic operation. I dont know if this is an better alternative ...

I found out that the variable causing the error "unable to find model variable: erosion_stress" is SSW_BBL, so I tried

#undef SSW_BBL

But I need this for bottom stress formulation. The error I now got is:

CHECKDEFS - no bottom stress formulation is selected.

Thanks again for the reply How do I individually keep #undef the variables? I tried to open the headerfile cppdefs.h (here norsjo.h) and add # undef erosion_stress without any luck. The same error as the previous post appeared when running ROMS: NLM: CHECKVARS_NF90 - unable to find model variable ...

Thanks for the reply I tried to undefine sediment in my cppdef.h file (called norsjo.h) and it worked for the variables mud_, mud_west, ..., etc,....., bed_biodiff and bed_tau_crit (line 2377-2627 in varinfo.dat). But unfortunately it didn't work for the variables further down, e.g grain_diameter ...

Hello, I'm new to the ROMS society so my knowledge is limited. I am turning here to hopefully get some answers. When running ROMS (on an local lake called Norsjo) I don't want the model to look for the variable "erosion_stress" in the initial condition file (or other variables related to sediment ...
