 WiseTex 3.0+: data open to a user
WiseTex 3.0:
• open XML input and output WiseTex
formats or custom
software
• “command line” version
New possibilities:
easy integration:
• upstream, with user- XML:
defined process models textile data
(e.g., braiding process)
• downstream, with user-
defined modles of
composite (e.g. meso-FE) XML: fabric
scripting: geometry
• parametric studies
• look-up tables (e.g., shear
angle) custom

 Workflow
1. Define the textile data
2. Build the geometrical model
... in TexComp
3. Control the resulting parameters
• calculate stiffness matrix of the
After that you can ... composite
... in FlowTex
... in WiseTex • calculate permeability of the fabric
• compress the fbric ... in VRTex
• shear the fabric • visualise the fabric
• apply biaxial tension to the fabric ... using the WiseTex – Abaqus
converting Python script
In all these cases:
• create an Abaqus model of the unit
• deformation – force response is
cell
calculated
• the deformed fabric can be stores
