Hello everyone,
Saad sent me the following email and I replied privately but think that
the rest of the group can benefit from the answer.
Why the mesh exceeds the framework that i defined in "outline"??
And in other places, the mesh does not take into account some areas of
the "outline"...
It’s a regular problem with BK or I made a mistake somewhere when I
defined my mesh generator??
Here is my response and the working t3m file.
Hi Saad,
When building an “analytic” mesh as is the case here, the key is to:
1. define your boundary nodes exactly as you require them,
2. and turn off the “Resample Outline” option.
The “outline resampling” process does not necessarily incorporate all supplied
geometric points. The same holds true for “soft lines”.
The reason is that, imagine you are supplying a shoreline (outline) that comes from a GIS
dataset where the point spacing is quite arbitrary and usually includes much more
detail than you would require for a mesh.
There is no reasonable way (that I can come up with) to automatically determine which
geometry to include and which geometry to discard.
I’ve modified your “outline” and attached the new t3m file here.
The process to modify your outline (in Blue Kenue) was as follows.
1. Resample the whole outline to 5m (using the “Max distance” method)
2. Split the resulting line at the 2m/5m boundaries (using “Split Selected Line”)
3. Resample the 3 short segments to 2m.
4. Merge all resulting lines to create the new outline (using “Append”)
Cheers… Martin
BTW: The NRC WEB people have fixed the problem with downloading Blue Kenue from the archive site.
However they are still working on incorporating the download pages into the new NRC WEB site. The new pages will have the links to download my very latest builds.
