Wrong code comment

[Kneib François]

Hi,

I think there is a mistake into the code comment : Ip2_FrictMat_FrictMat_FrictPhys.cpp line 40.
According the the documentation [https://yade-dem.org/doc/formulation.html#normal-stiffness] and the code, it seems that this Ip2 uses :

Li = 2 * Ri (i is a sphere)

as a typical length to transform Young modulus into stiffness :

Ki = Li * Ei = 2 * Ri * Ei

But into the code comment (L40), it's written : "(Ri.Ei/2) is the stiffness of a contact point on sphere "i", and to my mind it should be "(Ri.Ei*2) ..."

Don't you think so ?

You are right. Feel free to fix.
