Abstract

The software which converted from three dimensional model of woven fabric structures to STL file was developed. STL file is a general-purpose three-dimensional CAD data format and loaded by CAE (Computer Aided Engineering） system. The three dimensional modeler of woven fabric structures was applied as preprocessor of CAE for analysis of woven fabric properties. The analysis by FEM (Finite Eement Method) and MPS (Moving Particle Simulation) using three dimensional model of woven fabric structures was enabled by applying this software. This analysis allows the various physical properties designs of woven fabric.
