Post-processing#
PalaceToolkit includes modules for extracting and visualising simulation results.
Impedance extraction#
Extract antenna input impedance from Palace port output files:
from palacetoolkit.simulation import extract_impedance
freq_ghz, z_ant = extract_impedance("postpro/my_antenna")
This reads port-S.csv, port-V.csv, and port-I.csv, computes the
reference impedance \(Z_0\), and returns the complex antenna impedance:
S-parameter plots#
from palacetoolkit.s_plot import plot_s_params
plot_s_params("postpro/my_antenna/port-S.csv")
Generates magnitude plots of \(|S_{11}|\) (and \(|S_{21}|\) when available) versus frequency.
WSL note:
If plots do not open a window, install python3-tk and set matplotlib
backend to TkAgg in ~/.config/matplotlib/matplotlibrc.
Analytic reference values#
Compare simulation results against closed-form expressions:
from palacetoolkit.analytic import cpw_impedance, cpw_effective_index
Z0 = cpw_impedance(w=44e-6, s=25e-6, h=500e-6, eps_r=11.7)
n_eff = cpw_effective_index(w=44e-6, s=25e-6, h=500e-6, eps_r=11.7)
These use conformal-mapping formulas for coplanar waveguide (CPW) lines.
3D mesh visualisation#
Interactive viewer (notebooks)#
from palacetoolkit.viz import view_mesh
view_mesh("model.msh", transparent_groups=["air"])
view_mesh() now uses PyVista’s interactive notebook backend when executed
inside Jupyter (including docs notebook runs), so the rendered mesh remains
pan/zoom/rotate capable in the generated documentation.
