Error running SWAN

Hello all,

I do not know why my model doesnt work but I get this message:

C:\Users\jabanadestercero\Desktop\10Dec>rem exit
>>...End of SWAN run

Maybe, it is a problem of stability or there is some condition about the angle between the grid and the waves....

Thank you in advance

dear Javier,

Indeed the model is too big for swan 32-bit to handle, thus you see the stack overflow. There are two options, either you could use 64-bit linux version, or make your model a bit coarser. We don't have 64-bit swan version on Windows ready to use yet.

Hope this helps!

Hi Qinghua,

Thank you for your answer.

But the size of the grid is 0.0005 grades , that is more or less 50m! I think it is too big now, so if I can extend the size.... but I will try with a coarser model.

Edit:
I tried with a coarser grid:

And why does not this model run? the size is bigger but the message is

Terminating error: Allocation problem: array AC2 and return code is 41

Is for the 32bits, as well?

Thank you in advance

Regards

Hi Javier,

Your model is still too big. Just as Bert mentioned in http://oss.deltares.nl/web/delft3d/coast-/-estuary/-/message_boards/view_message/212820. I didn't mean the grid size, but the model size. You have 500*600 grids the first time, which is 300k grids. This exceeds the stack size swan can allocated. And this time you have 750*1000 grids, which is 750k grids. Still overflow... You should try 64-bit on linux platform or make your grid number less.

Regards,

Qinghua

I'd like to show you a game that many kids are now playing. Slope Game is a 3D browser game that necessitates a high level of concentration as well as gaming skills. The arrow keys are used to control the ball in this bizarre universe. Do not strike the red cubes, which are designed to bring you to a halt. You can see your score in the upper right corner of the screen while playing, and once you've smashed the red cube, you may submit your score to the leaderboard and compete against other players.

As far as I can tell, this is a result of the grid size being too large or a memory issue with the computer. However, after some testing, I can see that the simulation only uses up to 25% of the memory that is available, and the computation only requires two iterations (running reasonably quickly) to provide me with this memory. smash karts
