select edge size of both inner and outer edge of the cylinder totally 4-edges (including bottom edges, assign the map face on one the top surface and generate volume mesh if it's hallow cylinder,

If its solid cylinder then slice the cylinder at the centre like a square box, as attached in figure

ICEM can easily generate this type of mesh without manual splitting using O-grid method.

Is this what you need? (attached)
