Abstract

A method for numerical processing of microwave heating multi-physics fields disclosed by the invention comprises the following steps: A. Solve the minimum value of the multi-physics field coupling variational expression under the given boundary conditions to obtain the boundary value of the time-harmonic field The numerical approximate solution of the electric field and magnetic field of the problem; B. Reduce the time step of the thermal field numerical calculation in the microwave heating process by time scale transformation; C.

Description

technical field [0001] The invention relates to the field of computational electromagnetics, in particular to a method for numerical processing of microwave heating multi-physics fields. Background technique [0002] With the wide application of multi-physics numerical calculation methods, computer calculation has developed rapidly in practical applications. With the continuous expansion of the application range, especially in large-scale industrial applications, the microwave heating process often generates a large amount of calculation data in the numerical calculation process due to the large device size and material handling capacity, and the excessive calculation load It is unbearable for ordinary computers. At the same time, the huge calculation data will cause the computer to generate a larger error range due to error iterative calculations, resulting in serious distortion or even errors in the results. These factors have brought difficulties to the calculation work. ...
