Integrated Engineering Software has updated its Faraday 3D time-harmonic eddy current field solver, first released in 1994. The program provides accurate calculations for optimisation of parameters such as force, torque and power, and the eddy current calculations can be used for determining losses, which in turn can be used for thermal analysis input.
Using Boundary Element Method (BEM), Finite Element Method (FEM) or a hybrid of these technologies, design engineers can choose the solver that best suits their models. Boundary elements suit applications requiring the analysis of large open regions and exact modelling of boundaries, while finite elements may be more efficient for highly non-linear problems or transient analysis.
A key update has been the multi-threading of the 3D program. It now reduces design time while improving product performance via computer simulations. The speedup for a field simulation process is almost linearly proportional to the number of processors available to the system, and by taking advantage of both the inherent parallelisable property of the BEM, and the advancement in the computational power of desktop systems, it achieves excellent parallel scalability. The time dependant eddy current field can also now be simulated directly with the Faraday Transient Solver. Translational and rotational motion-induced eddy current fields can be solved with the finite element method as well.
