how to create a cylinder geometry, blockMeshDict
 

Hello Everyone
I want to create a geometry of cylinder and I want all the changes,
blockMeshDict, Boundary File et ControlDict File
P and U file

To create a cylinder have a look at the solidDisplacementFoam tutorial.

The remainder of the question is not clear to me…

do u need geometry of a cylindric domain or of cylinder in something else?

blocking should consist of 1 block with arc edges in 1st case.

p and U are boundary conditions, examples can be found in tutorials and manual.
