Based on the thermal balance equation of heater element, the matrix for the cyclic functional method is established and the rules to fill this matrix are represented detailedly in this paper.
The presented method selects only one cyclic symmetric sector of the structure as the finite element calculating model and establishes the complex constrained eigenvalue equation of the sector.
