Setting Up A CFD Problem | FEniCS CFD

In this video, we explore how to setup a 3D Unsteady Navier-Stokes computational fluid dynamic (CFD) problem in BERNAISE, Binary ElectRohydrodyNAmIc SolvEr, using FEniCS back-end for solving partial differential equations. This is a long but simplified video that has overlaps for creating a microfluidic computer-aided design (CAD), create a mesh for CFD, import a mesh into FEniCS, and finally, run a problem within BERNAISE / FEniCS. Please use the chapters if looking for a specific part. If anything does not make sense or you want clarification, drop a comment below!
