rename Elmer Equation Fluxsolver to Flux

Post by bernd »

For a better structure it would makes sense to rename the Elmer Equation Fluxsolver to Flux since it is a equation and not a solver. Even if it might be called Fluxsolver in Elmer. All Elmer equation objects do not end with solver.

See https://github.com/berndhahnebach/FreeC ... fluxsolver

Would be good if someone could give it a try or if you guys share your opinion.

I think it's a good idea. Homogenization of the small things is key to guide the bigger things ! :)

For me this is OK.

A related question @raback: is the result of the flux-solver used in combination with the electrostatic equation the same as i switch on ''Calculate Electric Flux" directly in the electrostatic equation?
"Calculate Electric Flux = False ! (default True)" is used in the "Equation = Stat Elec Solver" e.g. on page 67 in http://ftp.funet.fi/index/elmer/doc/old ... orials.pdf

BTW: the menue entry for Equation Heat was wrong too. Introduced in Dezember 2017. I wonder noone claimed about ... git commit 0c1f99a30cf3 fixes this.

git commit 9bfd947886d9 BTW: old files should still load. If you guys have any problems drop a post here.

FluxSolver takes any scalar field and computes a gradient or flux on it using the Galerkin (or DG) method. I think the "Calculate Electric Flux" just averages fluxes on nodes between the elements that share them. So there could be small difference.

Basically we would nowadays probably go with post processing that utilizes the FEM machinery. Sometimes this means having a separate solver for it. Like the AV Solver (using Hcurl basis for magnetic vector potential) has a separate postprocessing solver.
