open TELEMAC-MASCARET The mathematically superior suite of solvers

Hello everybody,

When I want to define the type of boundary condition on the frontier
of the mesh domain, I do exactly as they said in the Blue Kenue manual.

But I don't really understood, if I had to put the type of boundary conditions;
on the Red Mesh as in the falling picture or the multicolored one.

And which file exactly (geo,........ ??) used to define boudary type?



Futhermore, when I lauched the simulation I have the following screen :




Thanks in advance

Hi

The boundary condition are stored in a specific ascii file which is strongly linked to the geometry file.
In the geometry file, you should have at least the bottom (the other layer in red is not necessary)

So pleasecheck in the BK manual, you should generate the geometry file and also a second file (bc2 file)

Hope this helps

Hello C. COULET, and all other

The matter is that the red one is define as Bottom !

If I understood, I must generated the type of boundary condition,
with the same file which generate the geometry.


Thanks in advance

Hi

Create a new selafin file
Move the multicolored mesh in it
Rename the variable as Bottom and you will have a correct geometry file

Then start to create a new bondary condition file.
Otherwise, you could use Fudaa-Prepro to create a telemac project from the sole geometry file (it will generate the boundary file)


Hope this helps

Hello again C. COULET, and others,

As you wrote, I have generate a Selafin file (for geo), a bc2 file; and a *.cli
file as wrotten in the Blue Kenue manual.

My new question is : wich names to give ?

When I lauch with tose new file I have an error :



How, what shall I do ?

Thanks in advance

Best regards

the boundary condition file generated in BK needs to be edited by you (use wordpad) removing all of the info on nodes and elements leaving only the boundary info lines at the bottom of the generated file. The names of the files are up to you as specified in the steering (cas) file.

Actually, there's no editing required.

Once you have created/edited a boundary condition object or loaded it from a file (*.bc2) you simply have to select its child table object and save that to a cli file that TELEMAC will read directly.

NOTE: You also have the options of saving it to a csv or dbf file.

Cheers... Martin

Thanks Martin I have been saving the BCi file and not the attribute table and found it strange that I had to edit it for use (should have read the manual)

Hello Martin, Tony, C. COULET, and all the other,

I re-started form the begining, from the geo file I create a .bc2 file,
the create cli file from the child of the .bc2 file; it still doesn't work any more.

Thanks in advance

Hi
post the different files (eventually in a zip) because without any other information it's difficult to understand
