Method, system, storage medium and electronic device for establishing fabric simulation model

Abstract

The invention provides a method, system, storage medium and electronic equipment for establishing a fabric simulation model. The method includes: acquiring a fabric surface at an initial moment, and discretizing the fabric surface into quadrilateral mesh patches of different sizes according to different material properties; analyzing The initial coordinates of the barycenter of each quadrilateral grid patch; the initial Riemann metric tensor and the initial Riemann curvature tensor are calculated according to the initial coordinates; starting from the initial moment, the Riemann metric tensor and The Riemann curvature tensor calculates the internal deformation energy, combined with the force analysis, calculates the coordinate position of the center of gravity at the next moment; establishes the fabric simulation motion model according to the coordinate position. In the invention, the fabric is placed in the curved Riemannian manifold space for research, and the non-Euclidean geometric theory can be used in the invention to improve the existing fabric modeling theories and methods, and make up for the complex modeling, slow convergence speed and poor stability of the fabric in the Euclidean space. , the simulation effect is not good and so on.

Description

technical field [0001] The invention relates to the technical field of fabric simulation, in particular to a method, system, storage medium and electronic device for establishing a fabric simulation model. Background technique [0002] At present, the research methods of fabric model and simulation are usually divided into three types: geometric method, physical method and hybrid method. The fabric simulation technology based on geometric modeling only pays attention to the external manifestation of the fabric, and is more like an advanced drawing tool, which has the advantage of fast simulation; The way of simulating fabric structure can be divided into: discrete model, including spring-mass model, mesh model, particle model; continuous model, including elastic deformation model, aerodynamic model, finite element model, etc.; based on hybrid modeling The method adopts the geometric modeling method to model, and considers the physical properties of the fabric in the simulat...
