Generalized Cylinder Mesher
➢Used with the polyhedral volume mesher to generate an
extruded mesh along generalized cylinders
➢Generalized cylinders: bounding wall
with closed loop at each end
➢Generalized cylinder mesher
automatically detects suitable
geometries
➢Cells are extruded along the axis of the cylinder
➢Extruded prismatic cells reduce overall cell count and can
improve the convergence rate in some cases
