Public Member Functions
	PolarCoordinateSystem (std::pair< double, double > r_range, std::pair< double, double > theta_range, Bool3 periodic={false, true, false})

Public Attributes
const double	m_r_min
	Minimum radial distance (typically 0, but can be > 0 for annular domains)
const double	m_r_max
	Maximum radial distance.
const double	m_theta_min
	Minimum angle (radians, typically 0)
const double	m_theta_max
	Maximum angle (radians, typically 2*pi for full circle)
const Bool3	m_periodic

Detailed Description

Polar coordinate system parameters.

Polar coordinates (r, θ) where:

• r: radial distance from origin (r ≥ 0)
• θ: angle measured counter-clockwise from +x axis (radians)

Physical interpretation:

• x = r * cos(θ)
• y = r * sin(θ)
• z = 0 (2D system)

This is a value type (struct) following OpenPFC's "laboratory" philosophy:

• All members public and const (transparent, inspectable)
• Immutable after construction (functional style)
• No methods (operations via free functions)

m_periodic

const Bool3 PolarCoordinateSystem::m_periodic

Grid periodicity: {radial, angular, unused} Typically {false, true, false} since θ is periodic
