Abstract :
Field line visualization provides a valuable insight into complex flow patterns in electromagnetic devices. In this paper, a method for the construction of closed flux lines in 3-D quasi-static electromagnetic fields is presented. The seeding, i.e., the selection of which field line to represent is performed by weighting the magnetic flux on a specified cutting surface. Due to the discretization error present in the finite-element (FE) solution, the field lines are usually not closed. Therefore, an algorithm is introduced to provide the generation of closed flux lines.
