WebThe key thing is to set the dimensions parameter to CYLINDRICAL. This means that all vectors represent ( r, ϕ, z) coordinates instead of ( x, y, z ). The computational cell in the r direction is of size sr = r + w + pad + dpml, and runs from 0 to sr (by default) rather than from -sr/2 to sr/2 as it would for any other dimension. WebThere are three things to note. First, there is a built-in function electric_energy_in_box which calculates the integral of $\vec{E}\cdot\vec{D}/2 = \varepsilon E ^2/2$.This is exactly the integral in the denominator, divided by 2. In cylindrical coordinates $(r,\phi,z)$, the integrand is multiplied by the circumference $2\pi r$, or equivalently the integral is over … phil laycock baker tillyWebApr 21, 2012 · Stepping through block-by-block: we first create the stream function (using the default velocity and cylinder radius) and create velocity functions u and v.
