Detailed Description
As defined here, a cylinder is described by its two end points and its radius, specified in the json file as e.g. "start": [<x0>, <y0>, <z0>]",
"start": [<x1>, <y1>, <z1>]", "radius": <r>.

- Parameters
-
idx Linear index of the point to add.
- Note
- The linear index of a point
(j,k,l,e)can be retrieved using the subroutinelinear_index(j,k,l,e,lx)in theutilsmodule.

A GLL point of coordinates \( \vec{X} = (x, y, z) \) is considered as being inside the cylinder defined by endpoints \( \vec{p_0} \) and \( \vec{p_1} \) and radius \( r \) if it satisfies the following conditions:
\begin{eqnarray*} ||\vec{X} - \vec{X_0}|| &\le& r\\ 0 &\le& t \le 1 \end{eqnarray*}
where,
\begin{eqnarray*} t &=& (\vec{X} - \vec{p_0}) \cdot (\vec{p_1} - \vec{p_0}) / ||\vec{p_1} - \vec{p_0}|| \\ \vec{X_0} &=& \vec{p_0} + t \cdot (\vec{p_1} - \vec{p_0}) \end{eqnarray*}
- Parameters
-
x x-coordinate of the GLL point. y y-coordinate of the GLL point. z z-coordinate of the GLL point. j 1st nonlinear index of the GLL point. k 2nd nonlinear index of the GLL point. l 3rd nonlinear index of the GLL point. e element index of the GLL point.
