Selective re-meshing: A new approach to include mode stirring effects in the steady state FDTD simulation of microwave heating cavities

A new selective remeshing approach to efficiently utilize the finite-difference time-domain (FTDT) method for simulating 3D microwave heating cavities with rotating mode stirrers is presented here. The proposed scheme is implemented in a similar to 300L multimode applicator and the result compares favorably with a validation experiment. The proposed implementation of the selective remeshing scheme is efficient, in that the remeshing is done on the fly and the previous FDTD solution is used to continue the simulation as a single run of the FDTD solver.
