dynamic surface solution when zero load at float #1

Open petejan opened 8 years ago

Hi, I'm trying to simulate with this file,

sofs4work.txt

and get a compression error with wave heights above 2 m when the tension goes to zero. Last output

compression error (931) adapting, dt = 1e-005 adapting back, dt = 0.0001 compression error (1004) adapting, dt = 1e-005 compression error (1005) max adaptation level exceeded

Any thoughts on how to simulate this?

Thanks,

Pete Jansen

You can try increasing EI to 0.1 or 1 on chains and terminations. It's artificial, but should help numeric stability in low tension regions/periods and probably won't have much other effect.

Gents, do you have any "hint" which compiler to use? I am not a programmer - writing ugly python code for the problems I have to solve.

Kind Regards,
