I am working on reinforced fiber composites, after modelling the unit cell(R.V.E) of the composite various boundary conditions are applied. After this result is obtained. The results are element(elements produced after meshing)-oriented. I want the stress as a whole on the whole unit cell. I have tried measuring the forces on the faces by taking the cumalative of nodal forces on each face. However, the common edges creates a problem. Can you suggest any other methos of calculating the stress on whole body.

I am doing simulation of fiber reinforced composites, for that I have modelled a cubic REV. However , when I am constraining the opposite faces' node displacement sum to be 0 and coupling the nodes in each face in the direction perpendicular to the area, ANSYS is coming out . I have tried this on i7 processor with 8GB RAM system. I am confused if its a RAM problem or a model problem. If there are too many constraints if I apply coupling as well as constraint???
