Luc Scholtès proposed the following answer: Hi Panos, Jerome is right about how to define the material when appending your walls. Also, keep in mind that friction between different bodies is, by default, governed by the lowest friction angles of these 2 bodies (the interaction law is formulated such as: interactionFrictionAngle=min(FrictionAngleOfBody1, FrictionAngleOfBody2)). This means that you can set the spheres to wall friction angle between 0 and the sphere friction angle (30 in your example), but not above. A way to simulate "extreme" friction between the wall and the spheres would be to block some Degrees Of Freedom of the spheres in contact with the wall to avoid their tangential displacement (e.g., blocking X and Y components of the spheres if the wall moves along Z).
