mesh partitioner

Question

Hello everybody,

I would like to partition my mesh before being distributed by using user-defined overlap.
Is this possible in fenics?

thanks!

Answer 1

There is a facility to define the 'ghost level' when partitioning a mesh. You set the global parameter:
parameters["ghost_mode"] = "shared_vertex"

or "shared_facet".

thanks!
is there also possibility to set overlap = 4 for example?
So let's say I have my mesh, how do I actually call this options?

auto mesh = std::make_shared(12, 16,16);
parameters["ghost_mode"] = "shared_facet"
