Not enough? How about OddRoc support? All coming soon!

No? How about scaling workflows?

New curated database of wood materials is available for #FreeCAD. You may need to refresh your local cache to see it.

Messing around with Rocket Workbench features and I came up with this design. I call it Hoopskirt. I'll probably never build it, but it looks cool!

I think I've finally found a way to add generic fillets to fin shapes. Unfortunately it produces some odd visual artifacts with certain shape combinations, even though these don't seem to be part of the model. #FreeCAD #Rockets #RocketWB
Fin can showing fins with a square profile and round fillets Fin can with fins having an airfoil profile and airfoil shaped fillets. This shows visual artifacts that aren't part of the model

What started as a feature to add proxy objects as rocket components quickly evolved into a whole set of scaling/upscaling workflows and features. The next release will be bigger than planned!

Proxy objects for the Rocket WB that will allow you to replace simple objects like nose cones with custom drawn objects having odd shapes or more detail

CFD! Automating the workflow for doing multiple studies of a rocket to help determine stability. The current guinea pig is a 34 fin rocket.

I can't seem to get MPI to use all 48 threads on my ThreadRipper CPU. I can "only" use 24 processes for my CFD runs 😂

30 minutes for 8 parallel runs isn't too shabby!

On a totally unrelated note, CFD report generation is coming along nicely!

Multiple CFD runs for multiple Angles of Attack with a single click! Still a lot of work to do before releasing, but it works!

Next up... automating reporting.

I bought these boots in 2008 and they had the courtesy of disintegrating when I came IN the building so I guess I can’t complain 🤣
