Alireza Sadeghi is still having a problem:
Hello Bruno,

When I increase the number of particles, as I said in the previeus
massage, the strain tensor is not correct. In the code, I applied
compaction strian rate (negetive) in z direction in the deviatoric part.
Therefore, It should have negetive strain in the z direction. But now I
have:

Triangulated Grains : 12491
sym_grad_u_total_g (wrong averaged strain):
0.0271423 -0.00121828 -0.00169358 
-0.00121828 -0.00108962 -5.17863e-05 
-0.00169358 -5.17863e-05 0.00136745 

Total volume = 0.018195, grad_u = 
0.0271423 6.67822e-06 -4.62223e-06 
-0.00244324 -0.00108962 0.000223831 
-0.00338253 -0.000327403 0.00136745 

sym_grad_u (true average strain): 
0.0271423 -0.00121828 -0.00169358 
-0.00121828 -0.00108962 -5.17863e-05 
-0.00169358 -5.17863e-05 0.00136745 

Macro strain : 
0 0 0 
0 0 0 
0 0 0 

In addition, When I opened the micro strain in Paraview, there is no specific shape. However, when I open view in the controller, the shape of sample is correct. I don't know what should I do. All the conditions are the same, just I increased the number of particles. 
Thank you very much.

best Regards,

Alireza
