Hi,

I use two simple lines for left and right bank, the number set for across/along the river is 5 and 12(change to other numbers does not work too), but the result is so strange.
I can do correct T3 channel with example data files from Blue Kenue, and I compared the left/right bank i2s files, there seems no intrinsic difference here, but I just cannot generate correct T3 channel mesh using my own data files. Could someone tell me where is the problem? Thank you very much in advance!

b.t.w, it seems the attachments for *.i2s files is not sucessfull, so put the contents below.

Serrer OFFLINE Moderator Posts: 720 Thank you received: 304	Hi Viola, The channel mesher is behaving correctly. You have set the "AlongChannelInterval to 12 and that is what you get. Please note that this parameter specifies a length. (In your case 12m.) If you specify 1000m the mesh looks like this... Hope this helps... Martin

viola	Hi Martin, Thank you very much for that, I got it clearly now. I had thought both the two parameters are for the numbers of nodes in both directions, -_-!!! viola
