Re: ROMS 3.4 Stalling

I have the same problem with the revision 566. It seems to be stalling when it reads the initial NetCDF file.

Re: ROMS-SWAN Coupled System Users

John, I am using ROMS-SWAN to study the wave-driven circulation in a lagoon system off Western Australia.

Memory issue in ROMS/SWAN coupling application

In my ROMS/SWAN coupling application, there are quite a few times that the running model was terminated because the model requested more memory than that was assigned in the beginning. More specifically, my application has a grid size 240x480x8. It ran on 8 CPUs. 2 CPUs were assigned for SWAN and th...

Re: typos in radiation_stress.F

But then I could not pass the compilation. It complained that Sxy_psi is not defined. Actually I searched all files in ROMS subfolders and could not find its definition.

Is Sxyl_psi the temporary array you mentioned?

typos in radiation_stress.F

I think Sxy_psi in radiation_stress.F should be replaced by Sxyl_psi. There is no definition of Sxy_psi in radiation_stress.F. It appears 5 times in the code.

It only affects 2D applications.

Re: problems in INLET_TEST case

John, thanks for your quick response. I'm using ifort v9.1. I downloaded the newest MCT v2.5 and compiled it successfully without any complaint or warning messages, but the same problem still exists in ROMS/SWAN. My ROMS/SWAN code is the latest version, 258M. There is no Errfiles from SWAN. The mode...

problems in INLET_TEST case

When I ran ROMS/SWAN coupling test case INLET_TEST, the program terminated in initial.F where subroutine ocn2wav_coupling is called. It seems that SWAN was running normally because there were a number of SWAN output files, such as PRINT-00x, ***.mat-00x, point1-spc2d-00x, etc, but ROMS part was stuc...

I just tried this CPP flag. It solved my I/O problem. Thank you, Paul.

There are still other problems. but I think they are related with the configuration when I switch from ROMS v2.0 to v3.0. INLINE_2DIO is not available in ROMS 2.0, so I have to modify ROMS 3.0 as I did with ROMS 2.0.

Shih-Nan, I did do as you said, but it did not help. I got a little more progress in debugging the code, but still have no idea how to solve the problem. Here is what I found. The program aborted when it either read in 3D variables (u,v,T,S) in nf_fread.F or wrote out 3D variables in nf_fwrite.F. No...

Bottom stress in ROMS

Hernan, I am a little confused with the bottom stress calculation in ROMS. There are 3 ways for this calculation using either linear drag coefficient, quadratic bottom drag coefficient, or logarithmic formulation via bottom roughtness. Only one method should be chosen. I find bottom stress is calcul...
