[waves2Foam] Questions about the overtopping utility

Hi Mr.Jacobsen

I am having a question about the overtopping utility, i want to ask what are the three values are they the vectors x,y,z? and what are the unity [m³/s/m]? i tried to read the source code but i am not familiar the C.

Thanks again,

Rafa Marques

Good morning Rafael,

Could you please be a lot more specific of what you are referring to? There are a lot of places, where I can find a vector (x y z). Furthermore, I do not know, where you have found the unit [m^3/s/m], but it is a discharge per unit width.

Kind regards,

Niels

Hi Mr jacobsen,

Thanks for you reply and sorry for my impreciseness, when i use the overtopping functionObject, I obtain 3 values per timeStep (when using it with timeStep), and i don know what are this values (sorry about my ignorance) and thats my question?

But i have more doubts, when i chose the faceZone i need to be sure that the phase passes through the faceZone completely?

Good evening,

The vector is the directional overtopping (normal to the faceZone). I will not have access to the source for some days, but I think that the overtopping is given in m3/s.

Concerning the second question, it makes little sense. The utility measures the flux of water over a given faceZone. That is it.

Kind regards,

Niels

Hi mr.Jacobsen

Thanks alto for the quick reply.
What I mean is that, if I use a higher domain with the same overtopping a get a smallermassflow? Sorry I am asking because I not testedd it yet.

Sometime I have difficulties to explain my problem sorry about that.
