Question #293247 on Yade changed: https://answers.launchpad.net/yade/+question/293247
Jérôme Duriez proposed the following answer: Yes, this is what I meant (in case your non-spherical bodies are all of the same type, either Facet or Box, you may remove either Bo1_Box_Aabb() ; Ig2_Box_Sphere_ScGeom() or Bo1_Facet_Aabb() ; Ig2_Facet_Sphere_ScGeom()) This being said, I realize my lengthy answer may not be directly related to your initial problem, I am sorry... I now understand you have different material parameters (these en,es) for different bodies. Usually, YADE handles this at the bodies "material" properties level [1]. For instance, simulations with "FrictPhys" handle like a charm different friction angles for sphere-sphere and sphere-box interactions. We just put different values for the frictionAngle attribute of the sphere or box bodies' Material [2], and one unique Ip2 (Ip2_FrictMat_FrictMat_FrictPhys) does the job giving different local friction angles for sphere-sphere and sphere-box interactions. Here, the design of Ip2_FrictMat_FrictMat_MindlinPhys is flawed in my point of view (I'm not used to MindlinPhys, though) if these en,es,krot are material parameters that can be different among bodies. Because including these parameters in Ip2_FrictMat_FrictMat_MindlinPhys prevents playing with different parameters the same way as frictionAngle within FrictPhys (hence your problem).. I see two possible solutions to your problem, both involving modifying the source code - either modifying the source code of Ip2_FrictMat_FrictMat_MindlinPhys to detect the shape of interacting bodies and assign distinct en,es in accordance. From my point of view, this would not conform the classical YADE design I exposed in #6, I agree thus with Jan it would be "hacky" - removing these en,es from Ip2_FrictMat_FrictMat_MindlinPhys to insert them in a (new ?) material class. Which would make more sense, from my point of view. Further discussion would require other people more used to MindlinPhys than me. Hope it still helps....
