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! :)
This is Episode 1 in this series using FreeCAD and the CfdOF Workbench to work through various OpenFOAM cases. This is a 2D, inviscid, transient run.
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.
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! :)
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.
