The hardness and virtual incompressibility of diamond allow it to be used in high-pressure anvil cell.

In some fields, a measure of the incompressibility of a flow is the change in density as a result of the pressure variations.
From the en.wikipedia.org
Applying a Newton or Picard iteration produces a system of linear equations which is nonsymmetric in the presence of advection and indefinite in the presence of incompressibility.

The property of being incompressible
In fluid mechanics or more generally continuum mechanics, an incompressible flow is solid or fluid flow in which the divergence of velocity is zero. This is more precisely termed isochoric flow. It is an idealization used to simplify analysis. ...
(Incompressible) In thermodynamics and fluid mechanics, compressibility is a measure of the relative volume change of a fluid or solid as a response to a pressure (or mean stress) change.
An incompressible fluid is one whose density is constant everywhere. All fluids behave incompressibly (to within 5%) when their maximum velocities are below Mach 0.3.
An index of the resistance of an elastic body, such as a rock, to volume change.
