Re: Limited cores can be used for SWAN in the COAWST package

SWAN tiles its domain by dividing the longest edge into the number of cores. So your longest edge is 542 and that happpens to be in the x-dir, divide by 30 gives around 18. so each tile is 18x437. for coawst i need to have the tiles be square, so that we can combine them with roms grid to determine...

Limited cores can be used for SWAN in the COAWST package

Hi all, Recently, I encounter a problem regarding to the number of cores that can be used for SWAN model (the one in the COAWST package). I can only use 30 cores to run my SWAN_only case. But I can use up to 200 cores for the SWAN4120 (not that in the COAWST package). Are there any bugs in the COAWS...

Re: Lagrangian Drifters stick to the boundary.

Are the sticky floats always stuck? i.e. did they move at all? It's hard to tell for sure from the images you posted, but I get a sense that many of the stuck floats are in one-cell wide bays or corners, and it is very hard to generate a flow inside a one-cell wide bay that will move a float out of...

Hi Wilkin,
I am using the #define FLOATS option in ROMS.

Thanks,

Lagrangian Drifters stick to the boundary.

Hi all, I am using Lagrangian drifters to study the residence time in an estuary. Initially, I release 1612 drifters to surface of the estuary at 20140301 00:00:00. The initial locations of the drifters are shown in figure(a). But I found that after a 4-month simulation (20140301-20140630), most of ...

What are the equation that the lagrangian float scheme uses?

Hi all,
I recently use the lagrangian float scheme to estimate the residence time. But I didn't find the relevant equations used by the scheme and the references either. I want to look more in details about this scheme. So, does anyone know about answers?

Thanks,
Dan :)

Re: How does ROMS treat daily river_transport in the model?

Thank you Kate! I change the resolution of river forcing to be 15 min. As for my case, it is essential to resolve the salinity pattern in an estuary.

Many thanks!

How does ROMS treat daily river_transport in the model?

Hi all, Recently, I tried to add river discharge in ROMS model as a source point. In my ocean.in, I set: LuvSrc == T LwSrc == F LtracerSrc == F T I downloaded observed river discharges from USGS website. The observed time series is in an interval of 5 minutes. The river discharge (in .nc) for ROMS m...
