%% Minimal Surface Using Command-Line Functions % This example shows how to solve the minimal surface problem using % command-line functions. The files |circleg| and |circleb2| contain % the geometry specification and boundary condition functions, respectively. % Copyright 2015 The MathWorks, Inc. g = 'circleg'; b = 'circleb2'; c = '1./sqrt(1+ux.^2+uy.^2)'; rtol = 1e-3; [p,e,t] = initmesh(g); [p,e,t] = refinemesh(g,p,e,t); u = pdenonlin(b,p,e,t,c,0,0,'Tol',rtol); pdesurf(p,t,u) %% % You can also run this example by typing |pdedemo3|.
