Thanks.

I tried using the Subdivision method. But, it does not refine the surface
mesh. It performs subdivision and drastically changes the input geometry.

I am attaching a snapshot of what I want to do.

input.png is a snapshot of my input mesh.

output.png is a snapshot of the output mesh that I wish to generate.
