open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi All,

I was wondering why it is not possible to get the individual wave components infos (e.g. hs,tp,dir,real/im potential etc...) when running in spectral mode.
I used to use CGWAVE quite a bit and used that option often.This is quite useful to get info of each spectral component to make realistic surface levels fields etc..

From what I saw, ARTEMIS will only outputs the final Hs field ?

It seems possible to modify the code to output that infos ( in artemis.f and lecdon_artemis.f in the IF(ALEMON .OR. ALEMUL) THEN "bits" )...but I would be keen to get some guidance on the best way to do it.

(Plus it seems there has been some fairly big changes on the way/order computations are done between the version 6 and 7 ...the modifications I made in vers. 6 did not work anymore in 7...)

Any lights appreciated !

Thanks

simon

Hi All ,

Bumping you again about this..
I got to the point where my simulation is running fine in spectral mode...now curious to look at "combined" wave fields..

Hopefully my last message is fairly clear !

Any infos/help appreciated !

Hello Simon,

The way of doing you own calculations produce custom outputs is through the UTIMP subroutine (utimp.f). There you can use available variables to do your calculations and store them in the 4 private variables (set up in nomvar_artemis.f).

The problem is that you can produce only 4 variable outputs at a time, so I guess it is useless if you have a lot of directions/periods.

The only solution I can think of is to run Artemis in monodirectional mode for every discretized direction/period that makes up the combined spectrum. It should take more time to set up but the computations should last as long as the random one.

Best Regards,

Thanks for your help Costas,

I'll have a look to utimp.f
I tried to modify the source code but it looks like I am saving results of all iterations so it is quite confusing so far !

I guess running each component independently might be the easiest way to go .

cheers
