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!
A brief introduction to the Python computing environment is given. By solving the master equation encountered in quantum transport, we give an example of how to solve the ODE problems in Python. The ODE solvers used are the ZVODE routine in Scipy and the bsimp solver in GSL. For the ...
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...
2. We first solved the equation using a simple square domain, which we will call D1, using different grid sizes. This helps us profile how our solver behaves in ideal conditions for the framework and hardware. Then we imposed a slightly more complex domain, which we will refer to as D2...
