Steps to reproduce

1. Isogeometric modelling of spatial rod elements 2. Full friction contact modelling between the interlaced yarns 3. Create representative unit cells to perform virtual macroscale simulations 4. Use Hill-Mandel conditions and energy theorems to apply homogenised deformation gradients and extract stresses and their tangents 5. Store them in the database based on the given strain states
