Trouble representing terms for the momentum equation using Fipy

How would i go about representing the dyad (tensor product) in the following equation? I can't seem to figure out what terms in Fipy I should be using in general.

$Cauchy$

More specifically the resulting equation:

$Cauchy$

I'm mostly familiar with the transient and source terms, but I am at a loss on how to represent $Term$

Thanks,

Solution

There's more going on there than you're interested in (multi-phase with phase transformation), but see liquidVapor1D and liquidVapor2D for examples of implementing the momentum equation.
