Hi,
I finally managed to finish periodic boundary conditions implementation. I
announced it would take me two weeks but it did take six :-(
Sorry for that, I was quite busy and did not have much time for ff3d ...
It seems to work well, I attach here a convection-diffusion example. The use
is quite simple: since you only need to build a periodic mesh, for instance
mesh M = periodic(M,0:1);
says that M will now be a periodic mesh, periodicity is defined between the
faces 0 and 1 (xmin and xmax). You can obviously declare multi-periodical
meshes:
mesh M = periodic(M,0:1,2:3,4:5);
is a three-periodic mesh.
This only works for cartesian structured meshes, since it is much more tricky
to connect faces for unstructured cases ...
I did not checked Navier-Stokes, since I did not have time, I would appreciate
feed-back.
Best regards,
Stephane.
