open TELEMAC-MASCARET The mathematically superior suite of solvers

hello everyone,

I am new in tomawac and in wave modeling in general.
I am trying to understand the first equation, but I got a problem to schematically represent Teta (wave propagation direction).




in my research I didn't find a "scheme" representing this angle.
so My questions are
is Teta the angle of the tangent of a specific point on/of the wave.???
is teta an angle leading an axis parallel to the X axis (pointing in the same direction as the X axis) ??? by this way the angle teta is always (pi/2 or 90 degree). (I suppose we are in a Cartesian coordinate system)


Thank you

Josias

Hello

I am not sure to understand your question, you will find a scheme with teta p44 of the user documentation.

hope this helps

Hi

Thanks tfouquet,

Sorry if my question was not explicit/clear, I will try to make it more simple and clear...
