open TELEMAC-MASCARET The mathematically superior suite of solvers

hi everybody,

I have a couple of questions about the coupling t3d and tomawac, specifically the wave driven current procedure.

1) "BINARY DATA FILE 1 = ??",
How correctly use it?

I didn't find in the coupling example of tom the use of the #binary data file#, is this procedure implicit?, because I follow the procedure:
a- running a tomawac simulation with FX and FY as only one results
b- using this result file as binary data file 1 (input ) for my coupling t3d-tom.

2) RECORD NUMBER IN WAVE FILE,
I really don't understand this part, "last iteration" and its default value 1.... I thought if it is the last iteration we can access it by -1 like in python programming? is it the last iteration of all tomawac simulation ? or the last iteration of the coupling period? can we take multiple iterations into account?

thx for the help

Hello,

This way of using a result from tomawac makes sens if you are in a converged situation (i.e. a static problem). For a dynamic situation i would advise you to use a real coupling solution.

So for a static problem, as you did it, you calculate your Fx and Fy untill you converged with tomawac and then you indicate the record number to use the file in telemac2D/3D. Apparently it should work with record=-1 but i nerver tested it.

There is an example of this use in sandpit-t2d

Hope this helps
