imcompressibility

in fluid dynamics, incompressibility is a standard assumption for water at low speeds.

the model enforces incompressibility by adding a pressure correction step at each timestep.

we verified incompressibility using a divergence-free velocity field throughout the domain.

numerical drift can violate incompressibility, so we apply a projection method to fix it.

the solver assumes incompressibility and neglects density variations to simplify the equations.

under the incompressibility constraint, the flow adjusts pressure instead of changing volume.

to maintain incompressibility, the code clamps the divergence to near zero after advection.

incompressibility breaks down at high mach numbers, where compressibility effects dominate.

we checked incompressibility by monitoring the volume conservation error during the simulation.

the incompressibility condition links pressure and velocity in a way that stabilizes the flow.

imposing incompressibility can improve realism when animating smoke-like motion at small scales.

even a tiny violation of incompressibility may cause unphysical sources or sinks in the field.
