Detailed Description

template<typename T>
class Phyth::Field< T >

Base class for physical fields (scalar or vector)

Field is an abstract interface for any physical quantity that varies over space, such as:

• Scalar fields: temperature, pressure, electric potential
• Vector fields: electric field, magnetic field, velocity field

Template Parameters

T	The value type returned by the field (e.g., Quantity<Voltage> for scalar potential, or Vector3<Quantity<ElectricFieldIntensity>> for vector fields)

Example: class ElectricField : public Field<Vector3<Quantity<ElectricFieldIntensity>>> { [[nodiscard]] value_type GetValueAt(const Vector3<Quantity<Meter>>& point) const override { // Compute E-field at the given position return {0_V/m, 0_V/m, -1.0_V/m}; // uniform field for demo } };

class TemperatureField : public Field<Quantity<Kelvin>> { [[nodiscard]] value_type GetValueAt(const Vector3<Quantity<Meter>>& point) const override { return 300.0_K; // uniform temperature } };

GetValueAt()

template<typename T >

virtual T Phyth::Field< T >::GetValueAt ( const Vector3< Quantity< Meter > > &  point ) const

pure virtual

Get the field value at a specific point in space.

Parameters

point

Position in 3D space (Meters)

Returns

The field value at that point

This is the core method of any field. Implementations must handle coordinate bounds and interpolation as needed.

Implemented in Phyth::Electromagnetics::ElectricField, and Phyth::Electromagnetics::MagneticField.

Update()

template<typename T >

virtual void Phyth::Field< T >::Update ( )

inlinevirtual

Update the field state (for time-varying fields)

This method can be overridden to advance time-dependent fields (e.g., electromagnetic waves, changing boundary conditions). The default implementation does nothing.
