Jérôme Duriez proposed the following answer:
Hi,

As a general remark, I think you are not supposed to mix Ip2_FrictMat_FrictMat_FrictPhys() and Ip2_CohFrictMat_CohFrictMat_CohFrictPhys() functors.
Because of class inheritance Ip2_CohFrictMat_CohFrictMat_CohFrictPhys() should be enough.

Mostly, having two Ip2_CohFrictMat_CohFrictMat_CohFrictPhys(), differing
only with setCohesionNow value, is meaningless and clearly not intended
by the design of this class.

Did you have in mind something in particular mixing all these functors ?


Regarding now your issue with young material parameter, are you aware this may not be the particle Young's modulus ? (see the -- maybe elusive-- doc [*])

Actually in your case, young is not the particle Young's modulus because
you do not seem to use Hertz Mindlin contact law. Thus, a curve fitting
calibration step is mandatory before you can expect getting back
experimental results.

(And I did not understand the rescaling concept :-) )

Jérôme
