Multigrid method
About this app
Solve the Laplace equation (Dirichlet) via multigrid: the error at each grid level as a stacked 3D wireframe relief. Smoothers (Jacobi/Gauss-Seidel) remove high frequencies, restriction/prolongation/coarse-grid solve the smooth remainder — V/W cycle step by step, with error history and a solution heatmap.
