The course is designed to enable students to attack a variety of chemical engineering problems which lend themselves to solution by numerical methods as opposed to classical mathematics. Problems that do not fir the mold "use existing software" are illustrated. The students are encouraged to create their own software to solveproblems. For this purpose students are given an introduction to the Visual Basic programming language. Students are also encouraged to use more advanced methods in Excel. Examples and homework assignments are drawn from industrial experience when possible.
