open TELEMAC-MASCARET The mathematically superior suite of solvers

Hello,

I am using version 3.3.4 of BlueKenue and would like to use the Bed Tools to compute the shear stress from currents and waves. I have successfully used the tool in the past to calculate shear stresses from currents. I have recently run Telemac coupled with Tomawac and would like to use those results to compute shear stresses from waves but have encountered a problem.

In the window "Shear Stress Calculation (Waves)", items corresponding to Wave Height (m) and Period (s) are requested but the only options that appear in the drop menu are my t3v items (e.g. Velocity UV, Wind Along XY, Force FXY). However, my t3s items with Wave Height and Peak Period appear as options in the drop down menu for Depth. I have attached a figure showing the available options in each drop menu.

Has anyone encountered this problem or have a possible solution?

Thank you!

I forgot to mention that I did re-save my TELEMAC output files as "2D T3 Vector Mesh (BINARY MultiFrame) (*.t3v)" and "2D T3 Scalar Mesh (BINARY MultiFrame) (*.t3s)" and loaded those into a new BlueKenue session but I encountered the same problem as described above.

I think I've answered my own question.

PSed requires wave height & direction (2D T3 binary Vector Mesh) and period & direction (2D T3 Vector Mesh) as inputs.

The Tomawac results (wave height, period, and direction) need to be post-processed to convert them from separate magnitude and direction items to vector components and then to vector fields.

Yup, you did indeed answer your own question. Thanks

Cheers... Martin

Hi,
I am confronted to the same type of problem you mentioned a while ago.

when you mention : "The Tomawac results (wave height, period, and direction) need to be post-processed to convert them from separate magnitude and direction items to vector components"

do you mean Hm0 should be reprojected according to DirMoy as hm0x=cos(deg2rad(360-DirMoy+90))*hm0 and hm0y=sin(deg2rad(360-DirMoy+90))*hm0 ???

Regards
