Reology with Fortran program available
Posted June 7, 2017 at 12:11 by kindle
This phd on Reology may be interesting.
Code : http://www.vvpf.net/download.html
Here he talked about memory function and a big memory footprint which will need special treatment in programming.

I just send you the paper you asked, and it might be a use after all, for your problem.
If you look at Eq. (8) in the paper (see also eq 9.3 p. 210 in the phd thesis), you have a Gamma which I am using. What I am working on is fading memory. But you could let it have full memory (alpha = 1) and put I = shear rate (i.e. dot-gamma) and you would be calculating deformation. In the FORTRAN source code this is named Gamma (in viscous.f90).
Anyway, if you do use this approach, memory (as in RAM) can be a problem very quickly, but the integration trick in my phd thesis I mentioned above can solve this.
