In this node, the spatial dimension of your system is defined. It represents the bounds and the resolution of the system along the $x$-axis.
The node does not require any input from other nodes.
The Spatial Dimension node consists of 3 content fields that are used to generate the discrete spatial dimension. $x_{min}$ and $x_{max}$ represent the lower and upper bound of the spatial dimension respectively and $n$ is the number of points within this range.
Note:
The spatial dimension has been defined from -1 to 1 along the $x$-axis and divided by 128 points. The output is used to define the bounds of a harmonic oscillator potential as shown in the plot.
