Detailed Description

Unit tests for FM2DDynamic fieldmap class.

Tests cover:

Parsing & metadata:

• File parsing (XZ and ZX orientations)
• Frequency parsing and conversion (MHz → angular frequency)
• Field dimension retrieval (z-bounds)

Field evaluation:

• Point field evaluation via getFieldstrength()
• Uniform field correctness (on-axis behaviour)
• Bilinear interpolation for spatially varying fields
• Exact values at grid points (GridPointAccuracy)

Geometry & bounds:

• Behaviour outside z-range (no modification, outside flag)
• Behaviour outside radial range
• isInside() helper (including boundary semantics)

Physical behaviour:

• Normalization and scaling:
  • Electric field: MV/m → V/m
  • Magnetic field: Bt → μ0 scaling
• Projection of cylindrical components (Er, Bt) into Cartesian (x,y)
• Consistency between XZ and ZX orientations

Low-level kernel:

• Static computeField() correctness (host views, interpolation, projection)

API behaviour:

• swap() toggle (orientation handling)
• getFieldDerivative() throws (not implemented)
• getFieldDimensions(6-arg) throws
• getFrequency() correctness
• getInfo() does not crash

Robustness:

• Missing / invalid file handling
• Fieldmap dictionary caching (singleton behaviour)
• readMap() / freeMap() lifecycle correctness

Semantics:

• Field accumulation: E and B are accumulated, not overwritten
