SN-solver in milonga still in Feenox?

[tzhang0475]

Is the SN-solver from milonga still work in Feenox?

Unfortunately not. The FEM formulation should be easy. The FVM will take more time because FeenoX now assumes finite elements only.
It's on the TO-DO list, but I'm not sure when it will be ported.

Thx!

If you have the time to take a stab at it, please create a pull request and I'll happily merge it. Otherwise I'll do it but I don't know when.

Hey @tzhang0475 . At least for 1D, now FeenoX has support for neutron transport using SN. See the example at https://seamplex.com/feenox/examples/neutron_transport.html#reeds-problem

Feel free to try it out and see if you find any glitch.

@tzhang0475 the SN solver using FEM is up and running, even working reasonably well in parallel.
There are some examples in https://www.seamplex.com/feenox/examples/neutron_sn.html but I'll add more in due time.
You can also check https://seamplex.com/thesis/html/060-resultados/README.html (use some translation engine because the text is in Spanish).

Hi, good to know the SN model is back in feenox, I ll take a look and there maybe questions coming! Thx!
