Practical application of Computational Fluid Dynamics (CFD) using COMSOL Multiphysics and Wolfram Mathematica

This report delves into the practical application of Computational Fluid Dynamics (CFD) by simulating viscous channel flow through a sudden contraction in the laminar flow regime. The simulations were conducted using two distinct software platforms: Wolfram Mathematica and COMSOL Multiphysics. The primary goal is to compare the procedures and results obtained from each software, providing a deeper understanding of CFD principles and emphasizing the importance of validating simulation outcomes.
