Module regular 

Regular (non-singular) element integration

Adaptive integration for elements when source and field elements are different. Direct port of NC_RegularIntegration from NC_EquationSystem.cpp.

Constants

HIGH_ACCURACY_THRESHOLD

High-accuracy threshold requiring 13-point quadrature

QUASI_SINGULAR_THRESHOLD

Threshold for quasi-singular integration (distance/element_size ratio) NumCalc uses approximately 3.0

Functions

integrate_g_only

Compute G kernel only (single layer potential) for efficiency

integrate_h_only

Compute H kernel only (double layer potential)

optimal_quadrature_order

Determine the optimal quadrature order based on distance to element

quasi_singular_integration

Perform quasi-singular integration with adaptive quadrature order

regular_integration

Perform regular integration over a field element

regular_integration_fixed_order

Compute element integration with fixed quadrature order (no adaptation)
