2D Schrödinger equation simulation¶
The node outputs the state of the simulation at the current frame.
All the simulation data are stored for each frame. Whenever a parameter changes, all the data for the current simulation are deleted.
The simulation depends on all the previous frames. So if you suddenly ask for a frame that was not already computed and that is “far” from the last computed frame, the simulation can take a few seconds to compute this frame (since it has to compute all the previous frames).
- Output: 2d grid of complex numbers. The grid is formatted this way:
[z_11, ..., z_1n, z_21, ..., z_2n, ..., z_n1, ..., z_nn]
^ ----------- ^, ... ..., ... ..., ^ ----------- ^
n numbers ... ... n numbersThis output is fully equivalent to a n*n matrix.
- Offset: size of the 2d grid.This offset can help you to naviguate through all the data as if it was a matrix.
- Time-related parameters
Frame rate: frame rate of the simulation.
Duration: duration of the simulation.
Δt: simulation time spent for each second of animation.
- Precision-related parameters.
Dimension: size of the 2d grid.
Scale: scale of the simulation.
- Wave packet-related parameters
Center: starting position of the wave packet.
Number of waves: number of waves that compose the wave packet.
Spreading: spreading of the wave packet.
Potential: boolean expression of the potential (in function of x and y).
Obstacle: boolean expression of the obstacle.s (in function of x and y).
