Mmg2d: internal lines

With mmg2d, is it possible to define internal edges along which the nodes may move like on a boundary?
Thank you very much,

Best regards,

Xavier

Hello,

It will be possible in the next release 5.2.0 (develop branch for the moment) if there are several subdomains.
That means triangles with different references : in that case mmg2d detects the edges between the subdomains and treats them as boundary edges.

Best regards,
