Question #690280 on Yade changed:
https://answers.launchpad.net/yade/+question/690280

    Status: Open => Answered

Jan Stránský proposed the following answer:
> This means that I have to create 5 new files related to my new law

you do not have and actually I suggest to put all the code in one file (well, two files, one .hpp, one .cpp). Have a look e.g. at CpmMat [1,2], where all the stuff related to one specific material law is on one place.
The links I provided was just as a reference of actual implementation.

> can I follow the same implementation in each file as for
FrictPhys_CundallStrack ??

yes (in general).
For Material, follow FrictMat, for IPhys follow FrictPhys etc.

> How do you i integrate these 5 files of definition of the law in the
yade core code ??

There is no special integration (if I got your question correctly), just
put the .hpp and .cpp files in pkg/dem directory.

cheers
Jan
