Title:
TIME-DOMAIN HEAT CONDUCTION SIMULATION METHOD AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/041642
Kind Code:
A1
Abstract:
Disclosed in the present invention is a time-domain heat conduction simulation method. The method comprises: performing geometric modeling and mesh generation by using a finite-element mesh generation tool, and reading geometric information; setting parameters related to each region material during solid heat transfer analysis; constructing a basic equation for a thermal time-domain finite element to calculate the value of each element in an element matrix, wherein a linear nodal-based scalar basis function based on a tetrahedral element is used for a thermal finite element, and obtaining an element matrix of each element; by means of the numbers of each element, each node and each side, making elements in element matrices correspond to elements in a global matrix, wherein the global matrix is obtained by means of traversing, superposing and utilizing the element matrices; and performing iterative operation on each time step by means of the basic equation for a thermal time-domain finite element. By means of the present invention, an accurate time-domain heat conduction simulation result can be obtained.
