[CIG-SHORT] viscous_strain for MaxwellIsotropic3D

[Ikuo Cho]

Dear PyLith Developers

The values of viscous_strain decrease with an increase of time when the
viscoelastic property is given as MaxwellIsotropic3D. I confirmed
quantitatively that the "viscous_strain" represents the elastic strains
for some problem (a relation, 2*(rigidity)*(diviatoric
"viscous_strain")= stress, was established). 

 The values of viscous_strain decrease with an increase of time when the
viscoelastic property is given as PowerLaw3D. A relation,
2*(rigidity)*(diviatoric total_strain-diviatoric viscous_strain)= stress,
was confirmed in this case.
