Hello,

in the subroutine BORH, is it really possible to take account a Tetab angle which varies along the limit of my mesh thanks to the formated file.
I have write the following lines in my subroutine:
C Frontière incidente
rewind(26)
DO I = 4068,4987
LIHBORT(I) = KINC
read(26,*) hslu,dirlu
write(*,*) hslu,dirlu
c rewind(26)
HBT(I) = hslu
c HBT(I)=2.0D0
c TETABT(I) = 240.D0
TETABT(I) = dirlu
c PERT(I)=tplu
ENDDO
But it takes only account the HB not the TETAB from my formated file.
Have you already encountered this kind of problem?
Thanks in advance,
Camille

Hello

Not sure where your code is coming from, but I don't think HBT, TETABT etc are in use anymore. Assuming you're running the latest version, I don't see any reason why it shouldn't work with HB%R(I) and TETAB%R(I)...

Hope this helps - Noémie

Hello,

I am using a TOMAWAC spectrum file to impose boundary conditions for ARTEMIS and I always wondered if it is possible from a theoretical point of view, to take two (or more) spectrum point from TOMAWAC and interpolate across the ARTEMIS boundary? Technically at the moment only one spectrum can be applied at any boundary.
That of course would result in a varying Hm0, WaveDir, Period and directional spread, which is significantly more complex than varying Hm0 and TETAB/WaveDir across the boundary.

Costas

We (HR Wallingford) are currently working on this and the feature (use of several TOMAWAC spectra to inform the ARTEMIS boundary and discretisation) should be available in the next release.

Hello Noemie,

This is excellent news! It is very nice to hear that ARTEMIS is under constant development. There are some serious features added with each revision. This one will address issues that are bugging me for some time. I can't wait to get my hands on it. When (roughly) do you expect this feature to hit the trunk?

Costas

Hello Costas

Difficult to say when the extension to coupling with TOMAWAC will be available. Definitely before next release (V7P4). We are finalising the development and debugging one last testcase. When that's done, would you be willing to beta-test my branch? We're talking before Christmas hopefully.

Noémie

Hello Noémie,

I hope by 'next release' you meant v7p3! My upcoming project (a month from now) would benefit from this feature, so I would definitely test it when it's available. Let me know when.

Regards,
Costas

Hello Noémie,

I am currently using the version 6.1 of artemis. When I comment in the parameters file "DIRECTION OF WAVE PROPAGATION" with the same range of values of my formatted data file 1, the waves propagate not as much when the direction of wave propagation is activated in my parameter file. I attached a picture of comparaison. I do not understand why this is so different.

Hello Camille

It's difficult to help you without the files, but I should think you still need the line 'DIRECTION OF WAVE PROPAGATION' in your steering file even if specifying TETAB values in BORH.

BORH is called within the direction/period loop. The code requires to know your directions before then to discretise the spectrum into the NDALE directions to be run by ARTEMIS. By default it will assume a spectrum centred on 0 (default value for 'DIRECTION OF WAVE PROPAGATION') with a spreading of 20 (default value for EXPOS). This will lead to a different set of directions to be run in the model than if you specify a 'DIRECTION OF WAVE PROPAGATION' other than 0, which I assume is your case.

Hope this makes sense. In summary: keep the line 'DIRECTION OF WAVE PROPAGATION' in your steering file with a sensible value. AND specify your finer TETAB in BORH.

On a side note: any reason why you're using V6P1? It's quite old now, and if you're not required to using a specific version, I would suggest trying the latest tag.

Hope that helps - Noémie

Hello Noémie,

Yes it makes sense, so does it mean that I also have to specify the minumu/maximum angle of propagation and the number of directions ?
I used the V6P1 because,I suppose if i install the last version, I would have to adapt all my files to the new version? ex: not the same key words between versions?
