Re: error after svnupdate, sfmakedepend

Finally I fix the problem!!! It has been dificult to find the real error, cause it only appeared when I find the code line in makefile and commented it. In a step during the update, I used windows, and it put me a "beatiful" Â character on the name of the makefile file. So I updated again the code w...

Re: error after svnupdate, sfmakedepend

Dear Kate, I will try to answer some of your questions. The gmake version is 3.81. It s something strange, cause the make_macros.mk file are build and copy to the folder Build/, after that I get the error "the file doesn´t exist"m the same happen with abort.F90 I only run one build.bash at the same ...

Re: error after svnupdate, sfmakedepend

Hi kate, Thanks a lot for your answer. I thought that the error was in sfmakedepend, cause if i use the older one, the error dissapeared. Most probably, I am doing something wrong. When I run /build/bash, I get: rm -f -r core *.ipo /modelos/ROMs/projects/upwelling_paral_mpi/Build /home/francisco/mak...

error after svnupdate, sfmakedepend

Hi, I has been working with ROMs without problems, but yesterday I made a svn update of the code, and now when I execute ./build.bash , I get an error. I think the problem is on sfmakedepend update, if I update all the files except sfmakedepend, I don´t get any error. Anyone has any idea about this ...

Re: inverse barometer effect on a costal lagoon

Thank´s a lot for your help, finally I will try to use a lagoon model nested (1-way, off-line nesting should do) inside a shelf model (2D) to model correctly the sea level fluctuations.

Happy new year !!!

Re: inverse barometer effect on a costal lagoon

So, if I want to model the inverse barometer effect, should I use a grid big enough to have an atmospheric pressure gradient? Use a bigger grid will have a higher computational time cost, so I should use a nesting model, isn´t it?

Thanks a lot for your answer.

inverse barometer effect on a costal lagoon

Hi !! I am trying to model the sea level fluctuations on a coastal lagoon,after getting good result forcing the model with winds, I want to simulate the inverse barometer effect. I have use the preprocessor option ATM_PRESS with PJ_GRADP, but I don´t get any fluctuation on the sea level. As I unders...

Re: low sea level with wind forcing

Hi, After a lot of test done, messages in the forum read and a bit of luck, I has resolve my problem. I dont know if it ´s the right answer, but at the moment, I get the expected results. With bulk fluxes, using the value of BLK_ZW =1 instead usual one BLK_ZW = 10. BLK_ZW Height (m) of surface winds...

low sea level with wind forcing

Hi, I am trying to simulate a coastal lagoon, (max. depth=6m, area=170 mk2 ) only forcing with real wind data. I use the Bulk_fluxes, but comparing the ROMs data with the registred data for the same period simulated, I get smaller values with ROMs. Registered data is around 0.1 m sea level fluctuati...

Re: Serial faster then openmp

I can´t give you an answer, but I made a research about auto-optimization with OpenMP for Coherens(another ocean model) and one of the conclusion obtained were the use of more cpu dont mean that you model will run faster, depending of the grid use,the machine were you run the model, if you are readi...

modified rslice to plot 2D velocity (ubar,vbar)

Hi!! I wanted to plot velocity overlay with rslice of my 2D case, but I couldn´t manage to do it with the original rslice, so I have modified the code in a way that, if your file has ubar,vbar, rslice read it and allow you to make velocity overlay. The lines modified, are : Line 527 Line 2023 I have...
