Mate, you made me freak out. The deadline is yet to be hit.
The original deadline was sunday evening (as usual), but the mail titled "DELAYED!" talked about two days of delay.
Interesting that I haven't receive any email, probably my team hasn't registered successfully. Anyway my car is not ready to be submitted tonight. In this regards, AFAIR there was an option last season, that gives the chance to be used once for the whole season for later sending of the stl files. Is it still available for this season and how much time it will give?
I accept this message as you pulling the late delay card. Now you still have almost a day to go. This night, I need your submission.
I will send you the submission link as DM.
Unfortunately I already gave up from this race. The car is still not finished. Promise to be online for the next race, as there is enough time.

Good luck to everyone. There are some great looking cars!

It looks I am the only one without sidepods louvres and with fully extended sidepods.

some interesting concepts there, congrats everyone. One or two seem to have found the trick (or at least one of them) with the F1 style underbody tunnel with strakes.... wonder how long it'll take the rest to catch on :wink: :lol:

Nice. New interesting details emerge from those images. All cars seem to be respectably designed.
But i'll call Max's car as the winner of this round.

Are you not participating this year?
And it seems like GCBB is also missing. What a pity...

Couple of anteaters, a couple of platypuses and a lot of different sidepods. Very exciting stuff. Koldskaal didn't disappoint with the expectation of something wild as usual 😄

edit: Oh god my mirror mounts are missing :shock:

Now I'm concerned what else I may have missed... Oh no

No time unfortunately. Plus CAD and CFD is a little bit too much like work.

I did start there tbf, but couldn't make the cooling target so did some chopping

I can understand, I use CAD and simulations tools for work and MVRC it's like training for me, but considering that the results are pubblic and I am using my company name, I hope to not make bad impressions. It would be interesting to see a car designed by you.

When should we expect the results? This weekend or next one?

I am afraid, it will not be done this weekend. The following one should work. I encountered many problems, even user error with my own software #-o . At least MFlow will soon receive a new check, thanks to that.
And just a small tip for you guys, do not place special surfaces like engine inlets right on top of another surface. Please place such a surface a few mm away from other surfaces and make sure it intersects surrounding geometry.

I wasn't able to to make the deadline as I was really busy last month, but I've had some free time recently to make my car for the next round. Image

I've registered under the name Tolo Racing, hopefully I'll get a download link to the CFD package soon. I'll have to wait and see till then if the cooling design is too optimistic.

Holy $h!t :lol: :lol: :lol: :lol: That is EPIC!!!!

You might benefit floor load and tyre displacement by pressurising around the top of the floor LE though!

That is Legendary!!!!

Gotta love the ingenuity combined with proper modeling.

I just fear those gills might upwash the hell over that rear wing.
And, having no sidepods, it might be harder to control front wing upwash (check out how Mercedes is dealing with that).

Thanks! I think with the MVRC rules theres a lot space to do whatever you want above the floor there, but I'm going to wait and see what the general flow direction is around there before adding anything.

My idea with this cooling position was to be able to exhaust the cooling air in a good position, in between the rear wing and beam wing. Hopefully there should be a good amount of downwash there. If the loss from the gills interacts with the rear wing I'll have to change things.

I think in general there's a philosopical question about how important outwashing the front wheel wake is for MVRC compared to Formula 1. With a real car there will always be some corner condition where the car is yawing and the wheels are steered which will result in the wheel wake going under the floor - so pushing it further out will give benefits in this condition. But my understanding is MVRC is just looking at straight ahead, 0 degrees yaw, so we are optimising for a very different condition to a Formula 1 car.
