Fluid flow

From Mathematics Is A Science

We are to use discrete differential forms. The flow comes from a vector field and is a 1-form.

There is an example of this here: Modeling with discrete exterior calculus. The heat, $T$, is a 2-form but its dual, $U=T^*$, is a 0-form. So its exterior derivative, $dU$, is a 1-form. It's conservative though (no cycles).
