Error of using MakeAxialMesh ultility
Hello everyone,
I am trying to generate a very simple 2D wedge which is part of a cylinder water tank. I started from the begging by follwoing the example here
http://openfoamwiki.net/index.php/Contrib_MakeAxialMesh
However, I met the following errors

Can anyone help me with that?
Here are my files under folder 0 and my Gmsh file
