Enhancing RBF-FD Efficiency for Highly Non-Uniform Node Distributions via Adaptivity
Siqing LI, Leevan Ling, Xin Liu +3
Radial basis function generated finite-difference (RBF-FD) methods have recently gained popularity due to their flexibility with irregular node distributions. However, the converge…
