POLYFLOW - viscous heating for isothermal viscoelastic flow

Can one evaluate the viscous dissipation and the dissipated power on the flow domain for a viscoelastic flow?

The user should ask for the post-calculation of both rate-of-deformation and total extra-strtess tensors, respectively D and T. Next, in the graphic interface, a custom field functoin can be defined for the viscous heating [= T:D]. The total dissipated power is the integral of the viscous heating on the whole domain. Note that, in view of the symmetry of D and T, only six components of the upper triangle of the tensor are provided. In other words, when defining the custom field function, non-diagonal contributions have to be taken twice.
