open TELEMAC-MASCARET The mathematically superior suite of solvers

Dear all,

I am a new user of ARTEMIS and I am finding it difficult to assess TETAP correctly. I've read the user manual and forum, had a look at and ran the examples.. but it is still not completely clear to me how to determine TETAP, in particular for the liquid boundary condition.

The manual says:

- solid boundary conditions: TETAP= angle of incident wave attack in relation to the outward normal, expressed in degrees in the clockwise direction (then why is it =0 for wall 1 in the example port - case test 004 for artemis v6p2 ?)

- liquid boundary conditions: TETAP= non oriented angle between the forecast output direction of the wave and the boundary normal


I'm sorry to ask a silly question, but I've been wasting too much time thinking on it... probably it's easier than I think...

Thank you,

Giulia

Hi Giulia,

TETAP has the same definition for liquid an solid boundaries.
It's the angle, in degrees, between the normal and the expected wave direction at the considered point.

TETAP must be in the range 0°-90°
