Femsii is a software created to calculate magnetic fields distributions. On inicial stages it work with 2D plane symmetric problems, but there is a prototype for axial symmetric problems. Femsii use a GMSH mesh, physical properties and electrical current sources to create a magnetic field distribution.
Femsii is divided in three programs, pre.bin (pre-processing), solve.bin(solvin Ax=b), and pos.bin(pos-processing):
Some Femsii features:
-Galerkin Method.
-Preconditioner and solver can use SMP systems.
-Can use complex electrical sources.
-It's possible to visualice the rotation of magnetic fields on induction engines.
-Software design modular and scalable.
Actually Femsii has a account on rediris.es forge.
It's possible get the source code and some manuals.
