Using Matlab to Solve BVODEs

This is the third video in the Solving BVODEs 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/). This video describes how to solve sets of BVODEs using Matlab. It then solves the set of BVODEs from the example introduced in the first video. 0:00 Intro 1:04 Matlab Code for Solving BVODEs 1:54 Arguments for the BVODE Solver, bvp4c 2:49 Calling bvp4c 3:31 bvp4c Return Values 4:12 Supporting Functions 5:25 Formulation of the Example Calculations 6:22 The Master Function 6:57 The Derivatives Function 8:28 The Boundary Conditions Residuals Function 9:44 The Axial Dispersion Reactor Function 11:02 The Deliverables Function 11:59 Execution of the Calculations I hope you found this video to be informative.
