Hi All,
I am trying to clone a mesh so I can remesh the clone and transfer the
solution from the original mesh to the new one. (is that the best way to
do??)
I am seeing a segmentation fault while calling 'ghosting functors' inside
'prepare_for_use'.
(I do have 'coupling functors' attached to the original System.)
I believe it should work ... Do you agree?
Please take a look at the error below.
>> std::unique_ptr<MeshBase> mesh = _old_es->get_mesh().clone();
