Roughness plays an important role in determining how a real object will interact with its environment. Although roughness is usually undesirable, it is difficult and expensive to control in manufacturing. Decreasing the roughness of a surface will usually increase exponentially its manufacturing costs. This often results in a trade-off between the manufacturing cost of a component and its performance in application. In this paper we have modeled roughening of nanocomposite materials during both isotropic and anisotropic etching by using a level set method. It was found that the presence of two phases with different etch rates takes effect on the development of the surface roughness
