Is there a way to create partial yarns using the TexGen GUI on windows? I need it to assess phase changes between warp yarns. When there is a phase change between two warp yarns in a two-ply composite, weft yarns in the Unit Cell are not comprised of full cross-sections, but pieces of them. I have attached a side-view sketch of it for better illustration.

I think I figured out the solution. For someone having the same problem, you can translate a yarn by dragging the coordinate arrows in the respective direction.
Now I have another question on exporting TexGen model to Abaqus. I tried both dry fibre and voxel meshes and both seem to work fine. But is there a direct way to assign contacts or glued conditions between the yarns for mechanical analysis? I could see node sets created for boundaries but not for potential contact regions. Any guide on this is appreciated
When I export the Abaqus file for the dry fibre model, I could see the yarn surfaces defined for contact regions. However, the exported mesh does not look good as there are some voids at the yarn boundaries. Any help to avoid this problem is much appreciated.

TexGen file also lacks these voxels for some strange reason
Hello,
Glad you found the solution to your initial question as I'm afraid I didn't quite understand what you were trying to do!
As you've seen, contact surfaces are only generated in the dry fibre export.
The mesh in the dry fibre export is generated so that it is periodic and with complete elements. If you look on the opposite side of the domain you will will see the corresponding element formation on the other side of the textile. It is done this way so that malformed elements aren't formed by generating elements as though the surface had been sliced through at the domain plane. The decision as to which end of the domain the element is placed is based on whether the centre point of the element lies within the domain.
