GridFunction
Published configurations
Finite-element fields.
A grid function represents a finite-element field by coefficients and evaluates the local expansion \(u_h(x)=\sum_a u_a\phi_a(x)\). Interpolation constructs those coefficients through the supported degree-of-freedom functionals; evaluation and interpolation have separate timing boundaries.
Benchmarks
Evaluation
