pde 3D POLYGONS

i have FIVE 3D polygons in a cube as total 6 models(including cube ) .i want to mesh them as one model .so that the voulme of polygons is not overlapped by the mesh of cube

[jahanzaib ahmad]

for i=1:(length(A))

DT3 = delaunayTriangulation(A{i});

[C3,v3]= convexHull(DT3);

nodes=A{i}';

elements=C3';

model(i)=createpde();

geometryFromMesh(model(i),nodes,elements);

end

for j=1:(length(A))

pdegplot(model(j),'FaceLabels','on','FaceAlpha',0.5)

figure(j)

generateMesh(model(j));

hold on

end
