open TELEMAC-MASCARET The mathematically superior suite of solvers

Hello,

I am a beginner in BlueKenue and I don’t understand why the mesh is not correct. So if you can help me .
I am going to explain in more details what I want and what I have done.
I want to refine the mesh around the dikes. To do that, I have imported a shapefile where the dikes are drawn in bluekenue (each dike is represented by four lines). I have registered it and resample it (20 m). Then I put this file in the Hardlines option in the T3Mesh Generator already created. I have put these parameters in the T3 mesh Generator:
Resample Outline : Yes
Edge Growth ratio : 1.2
Auto Smooth mesh : Yes
Resample Lines only : No
Default Edge Lenght : 200

And I obtain something which is definitively not what I expected. The meshes are too big and with a strange shape I have put the image of the mesh in annex.


When I mesh without the dikes, I obtain a correct mesh.

And when I mesh with all the tributaries (which are represented by 1 line), the mesh is also correct.

Is there anybody who know what happen ?


Thank in advance

Strange
And hard to give you some advises without anymore information.

maybe you should post you T3M files here (if possible) in order to allow us to have a look on it

Thank you for your help!

I found the problem. It was in my Mapinfo file. I did not know how but in Mapinfo, I could not modify the lines representing the dikes, despite the fact that i was in the "change" mode. That is why, the lines are not resample in bluekenue. I copied everything in a new table and it works !
