Hi,

In r2957, I cleaned the code (including some pre-2955 code).
r2955 did include two duplicated code blocks, I removed that.

Jacob, your current test script does not handle fluid bridges between
distant spheres. In order to do that you need:

1/ Ig2_Sphere_Sphere_ScGeom::interactionDetectionFactor > 1 (else no
interaction geometry is created for distant spheres)
2/ and also Law2_ScGeom_FrictPhys_CundallStrack::neverErase=True (else
the contact law deletes interactions as soon as there is no solid contact).

The only problem is you can't do 2/ for Mindlin law, which will always
erase.
Chiara, would you agree to add a flag" neverErase" to Mindlin law? The
only change in the code would be at line 163:

if (uN<0) {scene->interactions->requestErase(id1,id2); return;}

changed to:

if (uN<0 && !neverEarse) {scene->interactions->requestErase(id1,id2);
return;}

Cheers.

Bruno
