Regarding Upper Convected Derivative

[Shyam Sunder Yadav]

Dear Prof. Lopez

I was trying to extend your formulation for the upper convected derivative in the header file "upper.h" to three dimensions.

I am stuck at the relaxation function for 3D.

Please let me know how I can extend the lines below in the routine 

static void relax_upper_convected 

to 3D

    foreach_dimension ()
      S.x.x[] = (R.x.x[]+L.x.y[]*(S.x.y[]+S.y.x[]))
      /(theta[]-2.*L.x.x[]);

    S.x.y[] = (R.x.y[]+(L.y.x[]*S.x.x[]+L.x.y[]*S.y.y[]))
      /(theta[]-L.x.x[]-L.y.y[]);

Thank you

Regards
