PolyTex: a parametric textile geometry modeling package

PolyTex is an open-source toolkit for geometry modeling of woven textiles based on volumetric images. It provides functionality such as geometrical feature extraction, local variability analysis and textile geometry modeling. A meshing module was implemented to generate voxel meshes. Generation of tetrahedral conformal meshes will be implemented in future release. Local material properties are assigned to each cell in the generated mesh, such that the anisotropic and heterogeneity are reflected. This image-based model is commonly referred to as a “Digital Material Twin”. The toolkit is designed to provide material scientists with accurate numerical models to predict composite behaviors while not requiring extensive experience in image processing and mesh generation. Hence, Application programming interface (API) for OpenFOAM and Abaqus is provided.
