Cylinder.Phi¶

Cylinder.Phi(r, phi, z)¶

Surface function of a cylinder

\[\begin{split}\Phi(r,\phi,z)= \begin{bmatrix}r\cos(\phi)\\r\sin(\phi)\\z\end{bmatrix}\end{split}\]

with radius \(r\), polar angle \(\phi\) and cylinder length \(z\).

Parameters:

rfloat: Radius
phifloat: Polar angle
zfloat: Distance ins z-axis

Returns:

poslist: Cartesian coordinates for given polar coordinates
