Hi, Dear Jerome, Thank you for your instruction. In my contact model, I use the bonded-particle model, so I just assume the cohension force is modeled in the bond. In that case, the parameter of cohension c is not explicit shown in the model. maybe it is the problem of my code. I will read the code and study how it is modeled in YADE.
Thanks a lot. kan On 6/5/08, [EMAIL PROTECTED] < [EMAIL PROTECTED]> wrote: > > Send Yade-users mailing list submissions to > [email protected] > > To subscribe or unsubscribe via the World Wide Web, visit > https://lists.berlios.de/mailman/listinfo/yade-users > or, via email, send a message with subject or body 'help' to > [EMAIL PROTECTED] > > You can reach the person managing the list at > [EMAIL PROTECTED] > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of Yade-users digest..." > > > Today's Topics: > > 1.
