During sunday i had some time for attempting a first test drive and i wanted to share some first thoughts.
Hi Roland, thanks for taking the time to do this.
As basis i used your CFD-Tutorial 1 - Elbow.
1) when linking to documents on Github, we FORCE to Show/open the RAW-Version of the document, This way the download will
succeed. I had some struggle to download a working PDF
We'll have a look at a better way when time permits.
2) Installation on LINUX
I was missing the Information that a 0.17-devlopment Version (maybe a Minimum git number ?) is needed.
If you only write that FreeCAD is needed people will install from the repository or the 0.16 stable release ...
Good point. We've added this information to the Readme.
I was able to install all libraries/dependencies BUT OpenFoam 4.1
I downloaded the deb-package and upon starting Installation, a red error message said "unable to install".
Since i am quite new to Linux Mint i didn't see any possiblity to find out what exactly was wrong ...
Perhaps if you would try try install on a clean machine maybe you are able to tell more about that ?
I'm afraid I have no knowledge of Linux Mint. It would certainly be possible (if nothing else, building from source), but I would recommend installing on one of the officially supported distributions listed at https://openfoam.org/download/4-1-linux/
to avoid a lengthy process. Failing that, the Windows installation is likely to be the safest option to avoid dependency headaches.
In SolidWorks/SolidWorks Simulation i am used to model the solid body and model/define the lids.
Per algorithm the program will evaluate the (internal) fluid body excluding cavities without flow condition
and will highlight the fluid region with some sort of "bounding box".
It took me some time to realize that for simulation in OpenFOAM you need to model the fluid body and apply there
all needed boundaries/goals.
It would be nice to have this Information as introductory sentence in the PDF.
Perhaps writing in the documentation that the "slip"-boundary Need to be applied to the OUTER wall
would make the info clearer (OK in FreeCAD it would be a struggle to select the inner walls,
but more precise Information wouldn't hurt)
Thanks, we'll try to consider this perspective next time we go over the documentation.
4) General first observation
Hard to tell for me how much programming work on Linux it is, but upon starting the CFD-Workbench,
maybe checking if all libs and dependecies and FreeCAD-Version-Number is/are OK would be a good idea ?
Agreed, and we actually have this in the pipeline.
