# QuasiUniformGrid

QuasiUniformGrid creates a near-uniform grid with local adjustments for snapping points and structure boundaries.

This option corresponds to tidy3d.QuasiUniformGrid (opens new window).

dl: Step size for quasi-uniform grid generation. The generated grid can be slightly smaller near snapped locations.

  • Type: floating-point number
  • Unit: m, mm (default unit), um
  • Constraint: greater than 0
  • Required field

# Advanced

dl_min: Minimum grid step size in the selected direction.

  • Type: floating-point number
  • Unit: m, mm (default unit), um
  • Default: 0

max_scale: Maximum ratio between two consecutive grid steps.

  • Type: floating-point number
  • Default: 1.4

NOTE

Local mesh refinement, snapping points, and layer refinement are applied when at least one grid direction uses AutoGrid or QuasiUniformGrid.
