CFD Simulation in 2D COMSOL 5.5 Laminar, Fluid flow around a circular shape || Beginners part 2

Hello, i am Abhinav and today i have simulated the fluid flow around a circular shape cavity in a mm tube to demonstrate the velocity gradient within the tube. This first part of the video has a laminar flow. To beginners this is an easy way to learn COMSOL MULTIPHYSICS 5.5 software, and basics of fluid flow. Thanks for watching my video.
