open TELEMAC-MASCARET The mathematically superior suite of solvers

hello all,

i was using tpxo file for telemac2d simulation and i want to use liquid boundary condition file.
can someone tell me how to make liquid boundary condition file or share an example..??

I have not used TPXO however,

If you are using Blue Kenue for mesh generation you can create boundary condition files (.cli) using:

With mesh already open; File > New > Boundary Conditions

Drag and drop the new boundary condition file into view and then you are able to create your boundaries and values etc.

Hello Safu,

Well, I have not worked with TPXO, but I have seen posts about it where the boundary conditions are created with BK (as usual, but not sure at all it is always like this).
I believe the best way to understand how to generate a BC file is using Baxter tutorial, in section 4.1.2. (Page 52) this topic is explained (how to generate it).

You can find the Baxter tutorial in the link below

I hope it helps,

Cheers,

i am sorry, i was asking the liquid boundary condition file not "boundary condition file" that you specified in bluekenue manual. i used tpxo for the tidal elevation and flow along the boundary. if i am correct tpxo give tidal elevation based on the location. instead of that for each boundary i want to give value of tidal elevation or flow rate for a period of time.

You can always prescribe depth HBOR for the boundary condition in the Fortran file for yourself?

If prescribing elevation in boundary conditions then LIHBOR(K) = 5

DO N=1,NPTFR ! For all Boundary points
IF LIHBOR(N).EQ.5) THEN ! If 5 for Type of Boundary Condition on depth
HBOR(N) = ?VALUE? ! HBOR(N) - PRESCRIBED DEPTH
H%R(NBOR(N))=HBOR(N) ! NBOR(N) - GLOBAL NUMBER OF BOUNDARY POINTS
ENDIF

Obviously edit this if you have more than one boundary with the elevation prescribed and to replace the ?Value?
Hope this helps.

Dear Safu,

Sorry about the misunderstanding. The word ‘condition’ confused me. What you want to do is to set a liquid boundaries file (liq).

Well, it is quite simple actually, either you want to set SL or Q for a period of time, what you have to do is to set a liquid boundaries file which relates SL/Q and time.

Find attached an example of a liquid boundaries file (you must consider that it depends on the liquid boundaries quantity you have in your model, in this case I have 2 boundaries, one with H prescribed and the other one with Q prescribed).

I hope it helps,

Cheers,

José Andrés.

P.S.: There are some posts about liquid boundaries with TPXO, I advise you to see them.
