Abstract

The invention provides a fabric simulation model building method and system, a storage medium and an electronic device, and the method comprises the steps: obtaining a fabric curved surface at an initial moment, and the fabric curved surface being discretized into quadrilateral grid patches with different sizes according to the difference of material attributes; analyzing the initial coordinates of the gravity center of each quadrilateral grid patch; calculating an initial Riemann degree gauge tensor and an initial Riemann curvature tensor according to the initial coordinates; calculating internal deformation energy according to the Riemannian degree gauge tensor and Riemannian curvature tensor of the current moment in sequence by taking the initial moment as a starting point, and calculating the coordinate position of the gravity center of the next moment in combination with stress analysis; and establishing a fabric simulation motion model according to the coordinate position. According to the method, the fabric is placed in a bent Riemannian manifold space for research, the non-Euclidean geometry theory is adopted, the existing fabric modeling theory and method can be perfected,and the defects that in the Euclidean space, fabric modeling is complex, the convergence speed is low, the stability is poor, and the simulation effect is poor are overcome.

Description

technical field [0001] The invention relates to the technical field of fabric simulation, in particular to a fabric simulation model establishment method, system, storage medium and electronic equipment. Background technique [0002] At present, the research methods of fabric modeling and simulation are generally divided into three types: geometric methods, physical methods and hybrid methods. The fabric simulation technology based on geometric modeling only focuses on the external appearance of the fabric, and is more like an advanced drawing tool. The methods of simulating fabric structure can be divided into: discrete models, including spring-mass model, grid model, particle model; continuous models, including elastic deformation model, aerodynamic model, finite element model, etc.; hybrid modeling based Methods The geometric modeling method was used to model the fabric, and the physical properties of the fabric were considered in the simulation process, taking into acco...
