Hi, Luc,

that is possible. But it is better to know, how many materials with 
different frictionAngles you have in your simulation. In this case, you 
can simply use 'x_y_z_r_matId' import.
If your each body has unique friction angle, you should create separate 
material for each body.

Because, if 2 bodies have the same material but different frictionangle:

body[0].material.frictionAngle=0.1     |     => It is not a code, just 
to show algorithm
body[1].material.frictionAngle=0.2     |

After that, body [0] will have a friction angle 0.2 as well.
