Question for 'ana_mask.h'

#1 Unread post by dhtjtks »

Hi all,

I tried to use 'ana_mask.h' to block some area of my domain, which have 100(i)*10(j) grids in interior rho point. When I looked at the results it didn't work like I wanted. Extra areas were blocked when I used parallel mode. However, if I used a single processor, it worked fine but also gave some strange numbers at the masking area. I remember I didn't get this error before when I used other computing system. I had zero values at the masking area before. Is this the compiler problem? I attach my 'ana_mask.h' and output file. Please help me.

Regards,
Lee

Maybe it's about your expectations. In serial mode, the size of the arrays is smaller than in parallel mode. It might even be unsafe to be setting Istr-2 in serial mode. In parallel mode you are guaranteed to have 2 or 3 halo points around all the edges on each tile.

As for the 9.9e36, that's in the NetCDF output, using the _FillValue for masked areas. Are those values from the NetCDF output or from print statements in the code?

Thanks Kate. The values from the 'ocean_his.nc'. But I remember the value was "0" for masked areas when I used ROMS3.0. Wasn't it?

I'm sure it was, but things change in the ROMS world. 0.0 is a valid temperature so not a very good _FillValue.

Then, it's o.k. I have to follow the rule.
Thanks Kate!
