Hello Liqing

If you mean you want test your contact law to check if you get well the 
value of stiffness you set, you can have a look at 
examples/normalInelasticity-test.py, which defines two spheres whith one 
moving with respect to the other. Value of tangential force is plotted 
at one time, and you can check stiffness value by this way. You could 
define a similar script to perform the checks you want.

    But be aware that a special class was defined to perform such tests 
in fact : 
https://www.yade-dem.org/doc/yade.wrapper.html#yade.wrapper.LawTester 
(but personly I did not use it)
