Hi

is anyone aware of a way to perform a mesh adaptation in 3D like in 2D with Adaptmesh?

Thanks,

Romuald

afaik, not with adaptmesh. I guess you need `tetgreconstruction` (see [this](https://github.com/FreeFem/FreeFem-sources/blob/master/examples/3d/refinesphere.edp)), other things like [mshmet](https://doc.freefem.org/documentation/mesh-generation.html#mshmet) or [mmg3d](https://doc.freefem.org/documentation/mesh-generation.html#mmg3d)

OK. Thx.

What I like with adaptmesh is that you can drive the mesh adaptation with a function like the source term f when you solve the poisson equation Laplacien(u) = f. Also, in the example, I see that I should get something similar with mshmet and tetgreconstruction even though less direct.
