In order to improve the design of an induction furnace and to optimize the charge melting, a COMSOL Multiphysics® application is developed. This application runs a furnace model. The inductor, supplied with an alternative electrical tension, creates a variable induction field B ⃗. Due to this field, an induced current appears in the melt inside the crucible. Thus, the charge starts to heat. The input tension frequency, the inductor properties and the melt material have a huge impact both on the heat quality and the meshing refinement required by the simulation. This application provides a user-friendly interface to easily set up a furnace configuration. The whole model is fully adaptable to most configurations. From the inductor electric supply circuit to the geometrical air gap size between the inductor and the crucible, most parameters are available to the user within the interface. Then, the mesh adapts itself to consider the specific requirements of the electromagnetic simulation field. This remeshing step is computed in a completely transparent manner for the user. Using a 2D axisymmetric formulation, configurations can be solved to quickly provide through the COMSOL Server™ app post processing results based on concrete industrial needs, such as the power distribution in the charge or the global efficiency of the equipment.
