Jan Stránský proposed the following answer: Hi Mohsen, > 1- I want to generate an 'elastic' body (so rigid bonds and clump idea > are not useful) with arbitrary shape such that: > i- it's surface should be smooth, to provide such feature i thought > may be arranging spheres with prescribed overlap (but with no force) could > be the answer. is this OK? if yes how to apply it in YADE? if not , is > there a better suggestion? ii- As the shape is arbitrary (suppose a 2D potato) and i need a > realistic response of the body, i have decided to fill the inside of potato > with spheres with overlap but no force generated ( like previous part of my > question); any better idea? if this is OK, what is modelling consideration > (any comment about forces, moments, contact law and ...)? > As suggested by Jerome, some contact models allow this feature. I use CpmMat for this purpose. Overlaping spheres may be used if such surface is sufficiently smooth for you. I am curious myself, so I will create a simple example and post it here :-) how many such potatoes would you like to simulate? 2- In new version of Yade, is it possible to capture polygon collision? > There are polyhedra implemented, including collision detection and one material law (repulsive force is proportional to overlapping volume). Polygons can be simulated as prisms. > > 3- Can i model a flexible membrane in Yade? Is there any new findings > after zuoguang's question [1]? > It is not possible in Yade currently. You have to combine Yade with other software or use different software, like Woodem (suggested by Vaclav in referenced question) cheers Jan -- You received this question notification because your team yade-users is an answer contact for Yade. _______________________________________________ Mailing list: https://launchpad.net/~yade-users Post to : [email protected] Unsubscribe : https://launchpad.net/~yade-users More help : https://help.launchpad.net/ListHelp
