Enum MomentumEquationForm 

pub enum MomentumEquationForm {
    Kinematic,
    DensityWeighted,
}

Which momentum equation the drag is being added to.

Upstream branches on UEqn.dimensions() == dimensions::force, looking the density field up only in that branch. A runtime dimension check has no Rust equivalent here, so the choice is an explicit enum on the model: the caller that assembled the equation is the one that knows which form it is in.

Variants

Kinematic

Kinematic momentum equation — pressure is p/ρ and density does not appear. The drag added is V·D(T), so D is a rate [1/s].

DensityWeighted

Density-weighted (force) momentum equation. The drag added is V·ρ·D(T), upstream’s dimensions::force branch.
