set_contour()

Adds contour lines/surfaces derived from a scalar field.

For pyvista.MultiBlock datasets, Plotter computes a global min/max across blocks and generates shared contour levels so contours are consistent across the full model.

Parameters

• name (Literal[...], default: "Flux (A/m)") — Name of the scalar field to visualize (must exist in mesh arrays).
  • "B-Mag (T)"
  • "Flux (A/m)"
  • "J-Mag (A/m^2)"
  • "Loss (W/m^3)"
  • "F Nodal-Mag (N/m^3)"
  • "F Lorents-Mag (N/m^3)"
  • "Heat Density (W/m^3)"
  • "Heat (W)"
• n_contours (int, default: 10) — Number of contour levels to generate.
• color (str, default: "red") — Color of the contour lines/surfaces.
• line_width (int, default: 3) — Width of the contour lines.
• **kwargs — Additional keyword arguments passed to add_mesh() when rendering the contours.

Returns

• Plotter — Returns self to enable method chaining.

Example

from pyemsi import Plotter

Plotter("mesh.vtm").set_contour("Flux (A/m)", n_contours=20).show()
