Abstract A new selective remeshing approach to efficiently utilize the finite‐difference time‐domain (FDTD) method for simulating 3D microwave heating cavities with rotating mode stirrers is presented here. The proposed scheme is implemented in a ∼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. © 2006 Wiley Periodicals, Inc.
