Node Design

Now that we can do all the cool things ex. presets and such, it's time to think more design.

Nodes

NOTE: Throughout, when an object can be selected (ex. for GeoNodes structure to affect), a button should be available to generate a new object for the occasion.

NOTE: Throughout, all nodes that output floats/vectors should have a sympy dimension. Any node that takes floats/vectors should either have a pre-defined unit (exposed as a string in the node UI), or a selectable unit (ex. for value inputs).

• Inputs

  • Scene

    • Time
    • Unit System

  • Parameters: Sympy variables.

    • type Parameter

  • Constants: Typed numbers.

    • Scientific Constant

    • type Constant

  • Lists

    • type List Element

  • File Data: Data from a file.

• Outputs

  • Viewers
    • Value Viewer: Live-monitoring.
    • Console Viewer: w/Button to Print Types
  • Exporters
    • JSON File Exporter: Compatible with any socket implementing .as_json().
  • Plotters
    • various kinds of plotting? To Blender datablocks primarily, maybe.

• Sources

  • ALL: Accept a Temporal Shape

  • Temporal Shapes

    • Gaussian Pulse Temporal Shape
    • Continuous Wave Temporal Shape
    • Array Temporal Shape

  • Point Dipole Source

  • Uniform Current Source

  • Plane Wave Source

  • Mode Source

  • Gaussian Beam Source

  • Astigmatic Gaussian Beam Source

  • TFSF Source

  • E/H Equivalence Array Source

  • E/H Array Source

• Mediums

  • ALL: Accept spatial field. Else, spatial uniformity.

  • ALL: Accept non-linearity. Else, linear.

  • ALL: Accept space-time modulation. Else, static.

  • Library Medium

    • NOTE: Should provide an EnumProperty of materials with its own categorizations. It should provide another EnumProperty to choose the experiment. It should also be filterable by wavelength range, maybe also model info. Finally, a reference should be generated on use as text.

  • TODO: "Modal" solver monitoring (seems to be some kind of spatial+frequency feature, which an EM field can be decomposed into using a specially configured solver, which can be used to look for very particular kinds of effects by constraining investigations of a solver result to filter out everything that isn't these particular modes aka. features. Kind of a fourier-based redimensionalization, almost).

GeoNode Trees

For ease of use, we can ship with premade node trees/groups for:

• Primitives
  • Plane
  • Box
  • Sphere
  • Cylinder
  • Ring
  • Capsule
  • Cone
• Array
  • Square Array: Takes a primitive shape.
  • Hex Array: Takes a primitive shape.
• Hole Array
  • Square Hole Array: Takes a primitive hole shape.
  • Hex Hole Array: Takes a primitive hole shape.
• Cavities
  • Hex Array w/ L-Cavity: Takes a primitive hole shape.
  • Hex Array w/ H-Cavity: Takes a primitive hole shape.
• Crystal
  • FCC Sphere Array: Takes a primitive spherical-like shape.
  • BCC Sphere Array: Takes a primitive spherical-like shape.
• Wood Pile

When it comes to geometry, we do need to make sure

Notes

NOTE: When several geometries assigned to the same medium are assigned to the same tidy3d.GeometryGroup, there can apparently be "significant performance enhancement"s (https://docs.flexcompute.com/projects/tidy3d/en/latest/_autosummary/tidy3d.GeometryGroup.html#tidy3d.GeometryGroup).

• We can and should, in the Simulation builder (or just the structure concatenator), batch together structures with the same Medium.

NOTE: Some symmetries can be greatly important for performance. https://docs.flexcompute.com/projects/tidy3d/en/latest/notebooks/Symmetry.html
