>Please be more specific
Absolutely.

1st, isotropic compression

2nd, add positive shear
 (O.cell.velGrad = Matrix3(0, 0, .1, 0, 0, 0, 0, 0, 0, 0))

3rd. Proceed with analysis for positive the distorsion value (shear strain)
 (abs(O.cell.trsf[0, 2]) > .5)

4th. add negative shear
 (O.cell.velGrad = Matrix3(0, 0, -.1, 0, 0, 0, 0, 0, 0, 0))

5th, Proceed with analysis for negative the distorsion value (shear strain) 
 (abs(O.cell.trsf[0, 2]) > .5)

6th, add positive shear 
(O.cell.velGrad = Matrix3(0, 0, .1, 0, 0, 0, 0, 0, 0, 0, 0))

We want to loop from the second to the sixth.

An image of the loop is shown in the URL below.
I want to obtain a curve (stress-strain curve of soil) plotting stress σ on the vertical axis and strain γ on the horizontal axis.
