Webin vector form as (u · ∇)u. We choose to numerically discretize the form on the left hand side, because it is closer to a conservation form. The incompressibility condition is not a time evolution equation, but an algebraic condi-tion. We incorporate this condition by using a projection approach [1]: Evolve the momen- WebSep 18, 2024 · Answers (2) So you want to plot a vector-function , where f gives you 3-element vectors at points in 3-D space. For that you might get what you need from quiver3. But in my experience (for what that's worth) such plots rarely gives me as good an illustration of what's going on as. I hope.
