coupling with COAWST

#1 Unread post by m567tej »

Dear all

I configured a coupled model (roms+swan) for different grids. it seems that evrything is good, it works and make results but after 45 day it seems that go to a kind of stop, not message not blow up and not do anything. I have just the results for first 45 day :!: .

after running each model separtely, roms model works completely for 1 year requested time simulation but swan stop without warning after 45 days. according to point table results, both of RTpeak & TPsmoo are equal to 25 sec. the swan .in file are included with

this looks like an issue with your swan setup. Did it give any Err* files? Is there any information in the PRINT files? Does your wind forcing go for the whole year? did you run out of hard disk space?

dear john, thanks for your reply

you right. the problem caused by wind forcing, I recreate the wind file and use idla=1 according to my instruction. swan fully working.
