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 ...

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 ...

Hi all, I got a weird ErrorLog.txt when I am using the LTRANSv2b to simulate the pathway of passive floats. Particle 228 jumped over u element after ********** seconds Particle 228 jumped over u element after ********** seconds Particle 228 jumped over u element after ********** seconds Particle ...

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,

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 ...

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

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!

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 ...
