Generating weave structures with WeaveGeo

WeaveGeo is GeoDict’s generator for woven structures. WeaveGeo contains generators for the three basic single-layer weaving patterns plain weave, twill weave, and satin weave. Additionally, user-defined weaving patterns can be created with the complex multi-layer weave command.

The origins of WeaveGeo lie in the industrial filtering sector. For example, simulations were conducted to improve the pressure drop of oil filters (Wiegmann et al., 2010) or of components in paper dewatering felts (Probst-Schendzielorz et al.) and forming fabrics. Furthermore, in several projects, weaves for sand control applications in oil and gas extraction and wastewater filtration (Knefel 2011, Knefel, 2011, Knefel and Wirtz 2009, Glatt et al., 2009) were modeled and optimized. Many other applications are possible, such as investigations of high-density multifilament fabrics with CFD simulations (Rief et al., 2011).

Material properties like pore-size distribution, flow resistivity (permeability, pressure drop), effective thermal and electrical conductivity, effective elasticity, effective diffusion, filter efficiency, filter capacity, and many more, can be computed directly on the geometry models, using other GeoDict modules, e.g. PoroDict, ConductoDict, FlowDict, ElastoDict, DiffuDict, or FilterDict-Media.
