open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi everyone,

I have a simple question and I didn't find the answer on the forum.
How do you convert the data of bed friction (Manning coefficient at each node) from SMS .2dm file to Bluekenue SLF file ?

The SMS's data file looks like that :
"
DATASET
OBJTYPE "mesh2d"
BEGSCL
ND 1347515
NC 662934
NAME "manning002"
TIMEUNITS seconds
TS 0 0

I tried to import the 2dm mesh on bluekenue but it isn't working, there is a mistake when importating the mesh.

I tried to use Chesher 2DM2BK module but I had an error message too.

To create a BK mesh, i copy-pasted the xyz coordinates of the nodes of SMS file into a .xyz file to work on it in BlueKenue.

Both error messages are in attached files

Hope you can help me, have a nice day,

Antoine

Hi Antoine,

Blue Kenue offers limited support for SMS files.
And ONLY of the format that looks like this:

MESH2D
E3T 1 206 1086 22
E3T 2 81 973 554
E3T 3 554 875 498
E3T 4 498 870 479
E3T 5 479 782 478
E3T 6 478 750 387
...

Sorry, you'll have to either get your data into
this format using SMS (if that's possible)
OR do some coding yourself...

Hi Martin,

Thank you for your answer.
The 3 numbers in each line are for x y z coordinates, is it right ?
I already dealed with this format copying the 1 300 000 lines into a .xyz file.

The manning coefficient data are in an other file...

Antoine

Hi Antoine,

Actually the E3T records define the elements.
The node locations are defined further down in the file.
Why not just write to the native BlueKenue t3s file format.
You can find the format details in the Reference Manual Appendix.

Hope this helps... Martin
