Feature Request: Adding Fixed Edges Within The Domain #28

Open angelmusonda opened 4 months ago

angelmusonda commented 4 months ago

Hi Flo,

I find your library extremely useful for my work.

I would like to suggest adding a feature to define fixed edges within the boundary. This would enhance control by allowing users to preserve critical edges for certain purposes.

Hey Angel,

thanks for your kind feedback. Your idea sounds very promising! I put it on my to-do-list and I will try to add that feature as soon as possible :-)

Cheers Flo

Great! Thanks @FloSewn

Hey Angel,

the "fixed-edges" feature is now available in the newest release v1.3.3. I also included a new example (input-file and cpp-file).

It is not yet possible to add fixed edges via CSV files, but I want to add that as soon as possible.

Maybe you can try it out if you want and tell me about possible bugs ;-)

Thanks again for your idea!

Cheers, Flo

Hi @FloSewn,

Thank you so much for adding this feature. It works well in most cases.

However, I've encountered two limitations:

1) It doesn't work if one of the fixed vertices lies on the exterior boundary. 2) The _tri2quadmodification breaks the fixed edges.

I'm unsure if these issues can be resolved, especially the second one, as it's still a work in progress.

Regards, Angel
