Luc Scholtès proposed the following answer: Hello Anay, I don't remember saying that the jcfpm is "better" than the bonded particle model of Potyondy and Cundall for modelling concrete... The thing is that the bonded particle model of Potyondy and Cundall is not available in YADE since it is a model available in PFC so that's probably why I suggested you to use the jcfpm. From my experience, the jcfpm works pretty well for modelling brittle materials since it enables to simulate high ratios of compressive to tensile strengths and non linear failure envelopes (is that what you are looking for?). Actually, the jcfpm is very similar to the contact bond model of PFC, with the "extra" possibility to define near neighbor interactions. Now, as mentioned by Robert, you need to have a look a the doc in order to defined correctly the attributes of JCFPM: https://yade- dem.org/doc/yade.wrapper.html?highlight=jcfpm#yade.wrapper.JCFpmMat It seems that you copy pasted something from a cpm example script in the following line concreteId=O.materials.append(JCFpmMat(type=1,young=young,frictionAngle=frictionAngle,poisson=poisson,density=2400,sigmaT=sigmaT,relDuctility=relDuctility,epsCrackOnset=epsCrackOnset,isoPrestress=isoPrestress,cohesion=1e6)) and, of course, it does not work since all these attributes are not defined in the jcfpm.
