SFEMaNS
version 4.1 (work in progress)
Reference documentation for SFEMaNS

It is used to initialize the magnetic field \(\bH\) and the scalar potential \(\phi\).
The inputs of this function are the following:
H_mesh
is the finite element mesh used to approximate the magnetic field. phi_mesh
is the finite element mesh used to approximate the scalar potential. dt
is the time step. mu_H_field
is a list of real. It contains the magnetic permeability of each conducting domains. mu_phi
is the magnetic permeability in the insulating domain where \(\phi\) is approximated. list_mode
is a list of integers which contains the Fourier modes approximated. As the mesh can be subdivised, we note that H_mesh and phi_mesh depend of the processor considered when doing parallel computing. Same goes for the list of Fourier mode list_mode
.
The outputs of this function are the following:
time
is the time when the computations starts. Hn_m1
is the magnetic at the time timedt
. Hn
is the magnetic field at the time time
. phin_m1
is the scalar potential at the time timedt
. phin
is the scalar potential at the time time
. Remarks:
H_mesh
. phi_mesh
. Here is an exemple where we use the function Hexact and Phiexact (so initial conditions satisfy the boundary conditions).
We note that the integers i and k have to be declared. It is done by adding the two following lines in the declaration of the function init_maxwell
:
We refer to the sections Examples with manufactured solutions and Examples on physical problems for more examples.
