I have to see average stress in a material (a cubical block) at each increment of time (number is 20, say) that has been pressed to a large strain. The number of elements are 27000.

When I try to find in Abaqus, it gives stresses on each element at each increment of time and data become too large to find average. For example there are 27000 values for one increment, 27000 for second and so on.

My question is that how can I find average stress in the specimen of 27000 elements at each increment? Is there any direct method to find out in Abaqus rather than calculating average by summing all and dividing by 27000?

Thanks.
