[Jerome Duriez <duriez@xxxxxxxxxxxxxxx>]

Hello. Trying to use the local moment rotation law by using 
"CohesiveFrictionalContactLaw", I give a look to class 
"CohesiveFrictionalRelationships", and I have two questions about line 
88 to 94 (in version 1318).
- first of all are Da and Db the radii of the spheres in contact ? I 
tracked this Da an Db in the sources and it seems to me that it is the 
case, but because of their names I wanted to be sure that they are not 
diameters...
- then it is written that the "2.0" that appears in the calculations of 
the various rigidities are "arbitrary parameters". Why introducing 
"arbitrary parameters" ?

I ask this question because I want to use the results (the values of 
parameters calibrated) of the paper mentionned in the class ("Plassiard 
& al") and the comparison would be immediate without this 2.0 
coefficient (even if I should recognize that with it, it is not so much 
more complicated...)

Jerome
