I'm now trying to generate geometry from stl file.
ImportGeometry from .stl makes too low density of vertices(and edges) to simulate because of approximation.
In this reason, I added more vertices to original geometry.
However, adding additional viertices without adding edges makes bad mesh boundary.
Is there any method to import all vertices of stl file or increse vertices density of geometry?

Here is an example. Read more: 2-D Geometry Creation at Command Line
t = 0:0.2:2*pi; % make sure the curve is unclosed (decsg throws an error)
r = 5 + sin(5*t);
[x,y] = pol2cart(t,r);
dl = [2; length(x); x(:); y(:)]; % [polygon; # of points; x; y]
gd = decsg(dl); % decomposition
[p,e,t] = initmesh(gd,'Hmax',0.5); % max side triangle 0.5
