Example 1: Create a circle

Create a circle named 'circle1' with center = (1,1) and radius = 0.25. The region inside the circle is called 'regionA' and the outer region is called 'regionB'. The exterior region is set to be the outer region. The exterior region is not meshed.

import pdetbplus.*; % import package
% Initial setting for mesh display
showMesh = true; % show mesh in plots

% Define center
center = pointObject(1,1);
% Define radius
radius = 0.25;
% Create Circle
e1 = geometryObject.createCircle('name','circle1','center',center,'radius',radius,'innerRegion','regionA',...
    'outerRegion','regionB');

% Make a copy so e1 can be used elsewhere
tmp = e1;

% Mesh the circle with Hmax = 2*pi*radius/20 and plot the meshed geometry
tmp.initMesh('showMesh',true,'Hmax',2*pi*radius/20);
