Rioual is still having a problem:
Hello Robert,

Here is a picture:
https://stratus.irstea.fr/f/5be74ddefd5c4c5c9fd1/
The granular material is squashed between the two cylindrical boundaries.
Heat Boundary conditions have to prescribed between the inner cylindrical 
boundary
 And the granular material  and between the outer cylindrical boundary and 
the granular
Material.
I hope this makes things clearer....

Best wishes

Vincent,

Robert Caulk proposed the following answer:
>>In my case, my granular packing is confined between two concentric
cylindrical boundaries >> this is not adapted to this case so ?

Boundaries as concentric cylinders does not make sense. It seems I do not 
understand your geometry. Please clarify the geometry of the packing as well 
as the exact types of boundary conditions you are trying to apply.

>> is it a big job to modify the source code to add neumann's boundary
conditions ? (in case question 1 is favourable to my case)

Depends on your C++ coding skills I suppose. I already started working on 
this functionality, but it was buggy and I did not see any direct need to 
spend time debugging it [1].

Cheers,

Robert
