Hello,
I have a question about the getStress() function (utils.getStress()) in my simulation (triaxial test under TriaxialStressController engine)
In fact my model is a box with the size of the box is (-0.1,-0.1,-0.1) and (0.1,0.1,0.1) and the model is non-periodic case.

To extract the internal stress of the specimen, I use getStress(), as I see in the document, for the non-periodic case, the V = 1, so in order to output stress for the whole specimen, it would be:
utils.getStress(boxVolume) 
The problem here is I want to avoid the boundary effect so I want to "getStress" of a smaller space inside the specimen, if I do, for example
utils.getStress(boxVolume*0.75), is that a correct to avoid the boundary effect? Because I don't know how V is considered and calculated in this function, can anyone explain?
Thanks in advance.
