Technique Documentation- Explosion with Maya Fluids

Fluid Effects:  A realistic fluid simulator based on simplified, incompressible Navier–Stokes equations for simulating non-elastic fluids. It is effective for smoke, fire, clouds and explosions, as well as many thick fluid effects such as water, magma or mud. added in Maya 4.5 (Wikipedia).

According to NASA, the Navier-Stokes equation describes how the velocity, pressure, temperature, and density of a moving fluid are related.  The equation indicates velocity instead of position.  Therefore, any object’s flow can be determined using the Navier-Stokes equations.

The application of this technique can also be useful in the study of river currents and bayou flows in the Louisiana landscape.
