The tracking of the interface (s) between the phases is accomplished by the solution of a continuity equation for the volume fraction of one (or more) of the phases. For the phase, this equation has the following form: (16.3-1) where is the mass transfer from phase to phase and is the mass transfer from phase to ... WitrynaStiff methods are implicit. At each step they use MATLAB matrix operations to solve a system of simultaneous linear equations that helps predict the evolution of the solution. For our flame example, the matrix is only 1 by 1, but even here, stiff methods do more work per step than nonstiff methods.

Not all functions have a unique inverse function. If g is a function of x that has a unique inverse, then the inverse function of g, called g , is the unique function giving a solution of the equation for x in terms of y. This solution can then be written as Defining g as the inverse of g is an implicit definition. For some functions g, g (y) can be written …
