Hello,
what I wrote some years ago in
www.opentelemac.org/index.php/kunena/blu...sh/reply/35561#25215 still holds since the structure of Blue Kenue t3s mesh files and MIKE mesh files are very similar. Maybe in the meantime DHI changed also a bit the structure in his ASCII mesh file, who knows.
Furthermore some advises, which at least I follow:
1. Unless you need some new, not much tested, functionalities in recent alpha beta BK versions, stick to the offical release.
2. If you import something in Blue Kenue, then save the object in a Blue Kenue native format before doing any operations. Especially I would recommend this for meshes from other solvers and ESRI shape files.
3. Analyse the mesh in Blue Kenue. Some meshes have degenerated elements, elements with zero areas, or something else. If so, then repair the mesh before doing any operations or even doing simulations.
Hope this helps,
Clemens
