Sorry for late reply I'm still very busy currently with my thesis. A very nice screenshot. You have made some "mark" on the spheres, it looks nice ;) As a remember currently if both objects have isDynamic==false, their interactions are not calculated. It should be obvious to write it that way. Maybe the simulation is slower not because of interaction between them, but because there is simply a bigger number of bodies... But I can't check it now. If you can wait till april, then I'll be able to help you :) -- # Janek Kozicki _______________________________________________ Yade-users mailing list [email protected] https://lists.berlios.de/mailman/listinfo/yade-users
