open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi everyone,
I'm a new user for Blukenue. When I generate a mesh file by using T3 mesh generator, there appears many over constrained and overstretched triangular elements near the long and narrow island. How can I make them more uniform and remove the over constrained element.
Here attached are the sketch images and .t3m files.
Many thanks!

Hi,

I haven't checked your zip file.
But have you tried to resample the line?

Try resampling it and uncheck the option "Resample Outline" before you run the T3Mesh Generator

And also, what is that long red line on the lower right side of the inner island?

Hi,
Thank you for your reply and it works.
The long red line on the lower right side of the inner island is actually a narrow long island.
However, there are still a lot of over constrained elements in the mesh. How can I fix them? Removing them one by one using the 'delete selected element' in T3mesh tool bar?

Best regards,
Lin
