jjn and I have spent some time CADing and CFDing some of our own 2019 wings. Having exhausted the Perrinn model, we are now starting to slowly rebuild bits of it in the hopes of having our "own" F1 car model eventually. The FW has been deliberately kept not "too" aggressive in order to focus more on the outwash generation with representative strakes and endplates, whilst the RW still currently has the 2018-modified endplates (still 2019 legal) but with custom main plain and flap with centre attachment. The changes which were made by modifying the 2018 spec to the 2019 essentially saw reduced down and outwash behind the front tyres, along with quite a substantial shift in aero-balance towards the rear. As such, the current setting angles and the like are aimed at exploring the 2019 spec in CFD whilst trying to offset some of that rearward shift. (note, this will be covered in an article we've also written to be released shortly!!)
My meshing process I think is kind of beginning to get robust enough to decrease the turn around time required for new CAD to be meshed... with all the simplifications and "hacks" I'm having to do in order to not blow up my home computer, it has been very tempramental as to whether it will generate or not... hence any robustness in the process is a welcomed sight!! Typical convergence residuals are also improving slightly as we go which, once again, is all good news.
Finally, from here, Vanja is going to be joining in on the project and will be looking at creating some different bargeboards and/or floor as his first contribution. These images still have the standard Perrinn parts for that, however, hopefully as time goes on, more and more of this model will appear in various colours and replace the grey bits.
