Hi Fab,

right, I did the same. This way it works with generating the .lqd. Good to know now, maybe we should write a short guide about nesting:)
But anyway, congrats for having a proper run completed, I'm not just there.

I still run in an error as the subroutine STWC1 says I'm asking for a Period/Direction outside the range of TOMAWAC spectrum.

I've already set my min. and max. spectral period in the art.cas to default.

Any Idea?

Regards, Tim

Fab	Tim, You should specify min and max periods in your ARTEMIS .cas file (not default values), taking care that ARTEMIS frequencies are included in the range of ones in the TOMAWAC spectrum. Regards,

Hi Tim,
I managed to workaround the issue I was having and run the boundary extraction. The exact command is:

converter.py generate_bnd Kiel_Fjord.cli Kiel_Fjord_geo.slf tom_KB_r4.slf Art.lqd --varnames "WAVE HEIGHT HM0;MEAN DIRECTION" --varunits "M;DEG"

I have made the following changes to make your computation run:

MINIMUM SPECTRAL PERIOD      			=2.6
MINIMUM ANGLE OF PROPAGATION 			=-220
MAXIMUM ANGLE OF PROPAGATION  			=-20

Min max angle of propagation is up to you to adapt it to your desired spectrum discretization.
I have made the following changes to make your computation run faster (for testing):

SUB-ITERATIONS ACCURACY FOR TETAP       = 1.
RELAXATION ON TETAP                 =0.4
DISSIPATION RELAXATION              =0.6

The computation completes, but I don't get results, for no apparent reason.

Since it is a phase resolving model it requires minimum ~7 mesh points (if I recall correctly) per wave length. Your maximum edge length of ~142, is totally unacceptable. So you need to rethink your model setup because your model area is too large. Costas

TimN OFFLINE Senior Boarder Posts: 67	Hello community, hi Costas, I just wanted to let you know I completed successfully several simulations. After rebuilding the ARTEMIS mesh, I got some reasonable results. I'm now doing some sensitivity analysis in my case study comparing ARTEMIS and TOMAWAC before going deeper into the coastal protection scheme. Again, thank you very much for the help and your patience:) Cheers, Tim
