Magnetodynamics with cohomology conditions
From ONELAB
Here we represent and induction heating eddy current problem that utilizes the homology and cohomology solver of Gmsh.
Contents
Problem definition
$T-\Omega$ potential formulation
$A-V$ potential formulation
Implementation
Indheat.geo: problem geometry and cohomology computation in Gmsh
Indheat.pro: weak formulation in GetDP
How to use
All the files (.geo and .pro) must be located in the same directory.
- Meshing the domain and computing the cohomology
Go to the directory and then type:
- gmsh indheat.geo -algo frontal3d -3
After the mesh is built, a file indheat.msh should have been created in the directory.
- Solving the problem with GetDP
In a Terminal, type (in the right directory)
- getdp indheat.pro -solve MagDynAVComplex -pos MagDynAV
- Showing the result
Open the file "jTO.pos" with Gmsh by typing "gmsh jTO.pos" in a terminal in the right directory.
Result
Boundary mesh of the conducting regions. Current density in the conducting regions.
