I guess the paraview offered by OpenFOAM website related has problem, it doesn't work. I download another one from www.paraview.org

Hi, everyone!

I have a question about syntax. In anlitycalCylinder (from tutorials) I came across next code

U.boundaryField()[3][0].x()
U.mesh().boundary()[4].Cf()[0]

What do [3][0] in the first case and [4]...[0] in the second case mean? Is it a some kind of element indexing? I've read Guides very attentively, but unfortunately there is no information at all.

Hope to get some help.
