WeaveGeo

WeaveGeo is GeoDict’s generator for woven structures. It 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).

New in GeoDict 2026

  • Significant improvement in speed when handling weaves with multi-filament threads in non-periodic domains.
  • Improvement of multi-filament thread packing for woven geometries.
  • Rectangular fiber profiles can now be chamfered or rounded.
  • Fiber segment length can now be scaled by cross-sectional area instead of diameter to improve the stiffness model.
  • Implemented a new scaling scheme for broadening and overlap.
  • The FreeWeave solver now accounts for fiber diameter and/or cross-sectional area when calculating broadening and overlap.
  • Introduction of iterative broadening in the FreeWeave solver. Broadening is now gradually increased during the first iterations until the target value is reached.
