Demo of Interface Mesh Generator

We provide several examples on using interfacemesh to generate an interface-fitted mesh satisfying the maximum angle condition in two dimensions. We refer to a simple interface mesh generator for detailed explanation of the algorithm and help interfacemesh for input and output arguments.

Circle

box = [ -1, 1, -1, 1];
h = 0.1;
phi = @(p) sum(p.^2, 2) - 0.5.^2;
[node,elem,interface] = interfacemesh(box,phi,h);
showmesh(node,elem);
findedge(node,interface.edge,'all','noindex','draw');

Flower

[node,elem,interface] = interfacemesh(box,@phiflower,h);
showmesh(node,elem);
findedge(node,interface.edge,'all','noindex','draw');

Heart

[node,elem,interface] = interfacemesh(box,@phiheart,0.5*h);
showmesh(node,elem);
findedge(node,interface.edge,'all','noindex','draw');
