and click on the "Run" button in the left panel.
Features addressed in this tutorial
- Right-hand-side term of a Poisson problem
- Onelab variables
- Boundary conditions at infinity
Additional information
This is the magnetostatic 2D model of an electromagnet. Only a quarter of the system is represented. Symmetry is accounted for by means of a Dirichlet boudary condition (bn=0) on the y-axis and a Neumann boundary condition (ht=0) on the x-axis. The coil has 1000 turns and is supplied with a current of 0.01A. A magnetic core of default relative magnetic permeability equal to (this value can be change by the user) is placed inside the coil. The boundary condition at infinity is accounted for exactly by means of a shell transformation (infinite elements).
