Publications

  • A tutorial of the immersed interface method (IIM) for fluid-solid interactions, in preparation. (This book will use the codes in a CFD package that I have been developing to cover the theory and practice of the IIM.)
  • An introduction to scientific computing with Matlab and Python Tutorial, in press with Taylor & Francis. (This book is intended to serve as a textbook for MATH3315 and MATH4315 – Introductory Scientific Computing at SMU.)
