Re: Why floats solution behave with anti-parallel speed-up?

Hi, I think that your problem of slowness even when you dont release your floats yet can be tweaked if you have the patience to test out a little modification in the code. the ideia is only call the floats when close to release time right!? You can try to edit the main2d.F and main3d.F and just afte...

Re: Near-bottom numerical instability over the slope

Hello again andré, all right, so your function/initial distribution is right and there is no error associated with the initial conditions. And yes, the hpge is sensible to the profile you impose, since the pressure at two z point would be different in steeper sigma coordinates. The thing with the ge...

Re: Near-bottom numerical instability over the slope

Hi there, seems that you had a lot of fun with this...and i think that gustavo have a good point. Are you really sure about your initial conditions and their configuration in the sigma coordinates? Because your rx values are already too conservative and even in other grids where the rx are higher it...

Re: Slow performance on SGI with Opterons

Hello Antonio, are you sure that you use the same compiler (including versions) and same flags over the runs(See the first lines of your log)!? Using intel compilers!? If so, maybe you should check the compiler flags or disable optimizations and check again the performance... The intel compiler have...

I can see that this kind ...

Re: what's wrong with the seagrid spacer?

I do NOT recommend avoiding the mex files with SeaGrid. Chuck Denham, the author of this tool, tried to make non-mex versions of the elliptic solver and the other mex files, but it didn't work out so well. If you don't use the mex files, you will get a grid, but it may be wildly nonorthogonal. Nice...

Re: what's wrong with the seagrid spacer?

I see this problem a long time ago, but i think u must try to disable the the mex checkbox .

:arrow: Open Seagrid, Select menu View, and uncheck the Mex box on the end of the window!

Check if works!

You cant use this together: #define ANA_FSOBC #define ANA_M2OBC with #define SSH_TIDES #define ADD_FSOBC #define ADD_M2OBC :!: U probably are overwriting the values in the boundary, using this 2 options ! The first's options set the elevation on the boundary to the values in ana_fsobc.F & ana_m2obc....

Inside of roms the attributes south , east , north , west refer to the Grid . More precisely if the grid has size (eta_rho,xi_rho) , then: The points of the southern boundaries are all the points (1,iXi) for iXi between 1 and xi_rho . The points of the eastern boundary are all the points (iEta,xi_r...
