Hi,

Thank you very much for this new version !


I observe a first bug. The program crashes and closes when the mesh is generated (T3 mesh -> Run)

Regards

Florent

Changing this to it's own topic.

Odd... I'll try it out. Thanks for reporting it!

Kindly,

Looks like you are doing something different than me and/or have different data. Therefore it is likely something specific.

Can you please try to narrow down exactly what steps cause the problem and send me as simple a set of reproducible steps and example data as you can?

Sorry for the troubles!

Kindly,
Alan

Same issue.

I just create a closed line, set it as outline of T3 mesh generator, it "run" -> Crash at "Initialize new mesh attribut"

I can reproduce now. Different options between what I ran and what you ran.

I'll debug to see what's going on internally...

Kindly,

Try turning "Auto Smooth Mesh" off. Do you still get a crash?

No crash with "Auto Smooth" unchecked but generated mesh is broken.

Not all outline geometry generates a broken mesh...

The Auto Smooth Mesh option is definitely the broken issue.

The "broken" mesh is a long time numerical problem that has been around since before I started maintaining Blue Kenue. Try adding a small epsilon to your growth ratio or a small epsilon to your default edge length. And try running again. What happens?

Changing growth ratio has no effect on generated mesh at all :(

As it is a uniform mesh with 10m cell size, it seems normal that growth ratio has no effect.
