Hi all,
I have a 2D mesh with different regions, like this:
I generated a mesh for this beam
Is there a way to highlight the 2 circles with different colors?
Many thanks!

Please see the .mat file for data. data.node is the nodal info, data.elem is connectivity, data.region1 is the coordinates for the left circular region, data.region2 is the coordinates for the right circular region. I'd like to use different color to denote these regions. Thank you!

load data.mat ;
tri = data.elem ;
coor = data.node ;
x = coor(:,1) ; y = coor(:,2) ; z = coor(:,3) ;
patch('faces',tri(:,2:4),'vertices',coor , ...
'facevertexcdata' , z, ...
'facecolor','interp', ...
'edgecolor','none') ;
hold on
c1 = data.region1 ;
c2 = data.region2 ;
patch(c1(:,1),c1(:,2),c1(:,3),'r')
patch(c2(:,1),c2(:,2),c2(:,3),'b')

tri = data.elem ;
coor = data.node ;
x = coor(:,1) ; y = coor(:,2) ; z = coor(:,3) ;
trisurf(tri(:,2:4),coor(:,2),coor(:,3),coor(:,3))
view(2) ;
c1 = data.region1 ;
c2 = data.region2 ;
ylim([-20 40])
patch(c1(:,2),c1(:,3),c1(:,3),'r')
patch(c2(:,2),c2(:,3),c2(:,3),'b')
It can be fine tuned to get all elements of circles and plot them in our own color....
