Letting P(x):=WxP(x):=Wx and using the fact that D2(exp(D)−I)2=I−D+O(D2)D2(exp(D)−I)2=I−D+O(D2) we get P"(x)=(I−D+O(D2))(−n(x+1)m)=−nmx.P"(x)=(I−D+O(D2))(−n(x+1)m)=−nmx. We got ourselves a differential equation!
Iteratively solve the pressure Poisson equation using the starred velocities. $$ \frac{\Delta^{2} p(t + \Delta t)}{\Delta x^{2}} + \frac{\Delta^{2} p(t + \Delta t)}{\Delta y^{2}} = -\frac{\rho}{\Delta t} \left[\frac{\Delta u^{}(t)}{\Delta x} + \frac{\Delta...
