Reproducing kernel triangular B-spline-based FEM for solving PDEs
A novel way to deal with instabilities of the triangular B-spline is developed. The reproducing kernel approximation technique is taken. The kernel correction term is calculated locally. We numerically compare the improved triangular B-spline with the conventional one.
