Chareyre proposed the following answer: Hi Arthur Out of the box, Yade is not capable of handling all possible combinations of shapes and physics present in the code. I think it will never happen, it would require that somebody implementing a new shape - say ellipsoid - is supposed to implement their interaction with all pre-existing shapes. It would lead to exponential growth of code that no-one can sustain. So, if you want to simulate something new, you have to implement some missing functors sometimes. You give examples here. > I just don't understand what do I need to do. I need to create another Law2 > for CylScGeom, right? But when I check to the different interactions law > there is only one "Law2_CylScGeom_FrictPhys _CundallStrack" which is not for > me. I would need a "Law2_CylScGeom_CpmPhys_Cpm". Does it mean that if I want > to create a cylinder, the only choice is a FrictMat? Yes and no. Chained cylinders should be CohFrictMat if you want them to simulate beam-like behaviour (see e.g. scripts/test/chained-cylinder-spring.py). But cylinder-sphere contacts will be only frictional (see chained-cylinder-roots.py). François Kneib is already working on cohesive sphere-cylinder at the moment. I hope he can release something functional soon. If he doesn't, then you will have to implement something on your side. > Do you know what is the difference between a ChainedCylinder and a > Cylinder, I mean do I really need a chained one? > You really need chained cylinders, else it is not a beam, it's a granular material where grains are cylinder-shaped. And in facts, there are no functors at all for Cylinders a.t.m. It is just a class between Sphere and chCylinder in the inheritance, it can't be used in simulations (until somebody implement functors for standalone cylinders).
