Dual BC
Please look at the paper in attachment. I would like to know how beams D and E in Fig. 2 on page 2 can be modeled by stressedFoam. Applying the left dual BCs is my question.
Thanks.

Dual BC
Hi,
How can a traction and displacement BCs be applied simultaneously in a face, please? For example, having tractionDisplacement and slip types BC in the same time in a face.
Thanks.
