Hi,

I am trying to use “Optiflow” implementation (https://github.com/flomnes/optiflow), for CFD optimization. During optimization the walls are moving but they would sometimes cross each other.
-> Do you know how compute nodes or edges distances ? and/or to avoid crossing (see pictures below)

I think your best bet would be to switch from adaptmesh to a more robust mesh adaptation library, like mmg2d. It is not interfaced in a plugin, but you can call it via exec.
