Solving IVODEs

This is the first video in the Solving IVODEs Supplement to SCoRE, a Self-Study Course on Reaction Engineering (https://buffalobadger.github.io/SCoRE/). SCoRE is based on the online book, “Reaction Engineering Basics” (https://buffalobadger.github.io/RE_Basics/). Many reaction engineering analyses require the solution of a set of initial value ordinary differential equations, or IVODEs. Often the equations cannot be solved analytically, and in SCoRE and Reaction Engineering Basics they are almost always solved numerically. Hence, it is essential to know how to solve a set of IVODEs numerically. 0:00 Intro 0:33 Overview 1:54 IVODE Solver Input 3:04 Derivatives Function 4:11 How IVODE Solvers Work 6:00 Possible Solver Issues 8:13 IVODE Solver Return Values 8:48 Formulating the Calculations for Solving IVODEs 11:02 Example Formulation 12:06 Solving IVODEs Summary I hope you found this video to be informative.
