COMSOL Tutorial | Inertial Focusing in Spiral Microchannel | Part 2 - Creating 3D Spiral in CATIA V5 

very useful, I really appreciate for sharing your experiences.

Thank you for sharing .I'd like to ask how to set Dean number?

Thank you for your very insightful presentation. Could you guide me on a site where I can download Comsol and Catia? I mainly work on macOS, but I could easily switch to Windows for Catia.

CATIA is enough for creating the 3D geometry? or using Inventor etc have more advantages? thanks
