3D Modeling
PetRos EiKon's Magnetic LN algorithm is an extension to the current gathering LN algorithm for prisms or polyhedra to include magnetic field gathering effects due to induced magnetization.
Our implementation of DC magnetic modeling is unlike the majority of techniques available at present. By extending the LN technique to magnetic effects, we are able to model interactions not only between multiple bodies, but also within a single body (so-called demagnetization effects).
