Demonstrates enhanced resolution in weak-discontinuous problems, indicating significant error reduction.
• An extended r -adaptive IGA framework is proposed for weak-discontinuous problems. • A Gaussian monitor redistributes geometric resolution using level-set interfaces. • Control-point relocation enhances interface resolution without mesh refinement. • Up to 65.7% error reduction is achieved with negligible computational overhead.
