OpenFOAM Baby Steps - 3D Flow Over a Wing (Episode 2)

3D Airflow Over a Wing

This is the second in a series.  You can start the series here.   The series follows my journey figuring out how to use OpenFOAM for something more than repeating tutorials that already exist!    Sometimes that journey gets a little rocky!   :)

The Search for an OpenFOAM GUI

Out of a nerdy curiosity, I have been interested in visualizations made possible by Computational Fluid Dynamics (CFD) and Finite Element Analysis (FEA) for some time.  It seems that OpenFOAM is a very capable, open-source option.  However, much of the setup and operation is through individual text files and command-line invocations.  For the 'recreational CFD-er', a Graphical User Interface (GUI) seems to be more productive.

Groovy Grading

Quick Update 

 I thought I was going to delve into SwiftBlock and understand the mysteries of setting curved edges.........not so much.  Those mysteries still elude me.  But, I got edge grading to work, so it wasn't a complete loss! :)

A Basic Wind Tunnel

The Short Version... 

I've attempted to get started with OpenFOAM before.  I generally get bored with the building-block approach to learning it, jump in too deep and quickly get discouraged.  I added an OpenFOAM category to this blog in an attempt to motivate me to take smaller steps and to remain committed for a bit longer.
