Default extrudeMesh for buffer in a pipe

I came across this problem while creating a mesh for a pipe with many bends using blockMesh and extrudeMesh.
As seen in the figure below , I created a pipe using the project feature and then used extrudeMesh to create a bend. But I cannot create the buffer as I wanted as I cannot increase the diameter of the pipe.


I think I need to use three different files to create the buffer zone in the pipe.

Can anyone please help me with this?

You could use extrudeMesh to create the pipe without the modified area in the buffer zone and then a Python script using this library ( to modify the node locations of the nodes inside the buffer. (Should not be too hard, because you know the z-coordinates of the buffer, so you can search for the nodes and modify their x/y values accordingly).
