open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi,everyone:

I'm reappearring the tide example with the TPXO database in TELEMAC2d_validation_v8p3. I use the TMD Matlab Toolbox to output the height and velocity directly. However, there're some unclear points on the h.out and uv.out files, which are controlled by the keyword BINARY DATABASE 1 and 2 FOR TIDE.

I) Should the number of points which I selected be the same as that in the boundary file(.cli)?
II) The TMD Toolbox can only output the u.out or v.out file alone. Do I need to merge u and v data when setting "BINARY DATABASE 2 FOR TIDE"? Or just choose u data file? If need, is there a common method to merge?

Hello,

If you want to use standard TELEMAC-2D with keywords BINARY DATABASE 1 FOR TIDE (or 2), you have to provide the expected format which is constituents for nodes on a cartesian and regular grid. After reading the tidal solutions, there is a step of interpolation of tidal constituents on the nodes (tidal boundary nodes for boundary conditions or every node of the domain for initial conditions) then the computation part to calculate water depth and/or velocities itself.

What do you want to do? Compute tidal constituents (H, U and V) for every tidal boundary node and prescribe water depth and velocities boundary conditions from what you have computed from TMD Matlab Toolbox?
In that case, whatever the format you use, you have to modify the current implementation of the TPXO module to jump the interpolation step and do not use the keyword BINARY DATABASE 1 FOR TIDE (or 2) as you will not be able to use it.

Hope this helps,

Hi, I want to ask, if possible, can you please show me the file (.out) for the binary database 1 and 2 for tide.

Hello,

You have some regional solutions available here:

I already have the TPXO09, both the h and u files. but they are in ".nc" format, and I don't know how to prepare them into ".out" format.

Hello,

The best way to get the TPXO global solutions is to ask to register to the owners:
www.tpxo.net/home

The TELEMAC system does not own these solutions, it only provides possibilities to use them.

Hope this helps,
