Differential equations POLYMATH integration

Method (b). Numerical integration of the four equations, (3) to (6) is accomplished with ODE, either Constantinides or POLYMATH. Alternately, the material balances (11 and (2) and only the two differential equations (3) and (4) can be solved together. This procedure is better carried out with POLYMATH ODE. [Pg.102]

If we want to start the integration using the marching technique (Euler, Runge-Kutta, or using any subroutine from Polymath, Matlab, or IMSL libraries for the solution of initial-value differential equations, see Appendix B), then we need to assume a i(0) or X2(0). Suppose we choose to assume xi(0) = x"(0), where n refers to the n h iteration (for the initial guess, it will be = 1). Then, >C2(0) can be easily and directly computed from the relation... [Pg.318]

POLYMATH. AIChE Cache Corp, P O Box 7939, Austin TX 78713-7939. Polynomial and cubic spline curvefitting, multiple linear regression, simultaneous ODEs, simultaneous linear and nonlinear algebraic equations, matrix manipulations, integration and differentiation of tabular data by way of curve fit of the data. [Pg.12]

However, if you do not have that much time or your hand.s to form a tabic and use Chapter 2 integration techniques, then use Polymath to solve the differential form of mole balance equation (2-6) and the energy balance equation (1.3-14) simultaneously. [Pg.605]
