Radiation Stress Representation

Postby liegefkw@gmail.com » Thu Mar 22, 2012 14:09

Hi Mohiders!

I'm trying using MOHID couple with REF/DIF to study sediment transport near a mouth of a stuary in south of Brazil, and i have some questions about how MOHID handles waves.

My problem is: when I import the results of REF/DIF to MOHID, the vectors representations of Radiation Stress (wave stress x and wave stress y in HDF5), seems wrong, for exemple: for a incident wave of south quadrant, MOHID shows vectors pointing to south. I know that it is wrong when I import to MOHID, because I checked my results from REF/DIF and it are right.

In this way, the results of "wave stress x" an "wave stress y" in Mohid Postprocessor are the representation of Radiation Stress (Sxx and Sxy) or I'm confused with something else? In case to be the representation of Radiation Stress, can Mohid making some modifications in radiation stress?

Is there a documentation that explain how MOHID handles the radiation stress?

Another question is: In REF/DIF the incident wave angle is with respect to normal shore and I supose in MOHID it is true too, right? Or in MOHID the incident wave angle is with respect to North?

I hope I've explained myself well.

Best Regards,

Liége

Hi guys,

Try here:

Mohid wiki has more information on the model.
Recently a book also came out:

Hope it helps!
