Extended r-adaptive isogeometric analysis for weak-discontinuous problems

Key Points

• The aim is to develop an extended r-adaptive isogeometric analysis framework for weak-discontinuous problems.
• Proposed an extended r-adaptive IGA framework for weak-discontinuous problems.
• Implemented a Gaussian monitor to redistribute geometric resolution using level-set interfaces.
• Utilized control-point relocation to enhance interface resolution without the need for mesh refinement.
• Achieved up to 65.7% error reduction in problem resolution.
• Maintained negligible computational overhead during implementation.
