# What type of constraint is the homogeneity of a fluid?

Suppose we have a homogeneous fluid (may or may not have viscosity). Is the constraint due to homogeneity a holonomic constraint? Thanks.

1. What do you mean by homogeneity here? Constant mas density? 2. Do you mean holonomic constraint in the sense of the classical mechanics of systems of particles? –  joshphysics Apr 30 '13 at 15:55
