Batch Reactor Calculation Options
The tolerance for the integration method and tolerances for equilibrium calculations are defined in this window.
Usage
LSODA Tolerance
You may define the tolerance for the integration method, LSODA (Livermore Solver for Ordinary Differential Equations, Variation A).
Calculation Options
Choose one of the following two options :
Calculate Equilibrium at Each Time Step: Equilibrium calculations are done at each time step.
Use Equilibrium Calculation Tolerances: Equilibrium calculations are done only if the change in temperature, pressure or concentration between successive time steps is greater than the specified tolerance. It is recommended that these tolerances should be used if the problem involves electrolytes.
Equilibrium Calculation Tolerances
If no value is supplied than the absolute Temperature difference and the absolute Pressure difference default to 0.2 and relative Concentration difference defaults to 1.0E-6.
