[MVRC] Mantium Virtual Racecar Challenge 2022 (Grand Prix Cars)

[LegendaryM]

Congratulations everyone and GRaph especially for making such a big step. I thought I'd done enough to win but you all put on so much performance! I think I'm having a few correlation issues as well as I did a Long run and was above the cooling target.

I'm not going to have too much time to develop for the next race or two as my work has picked up/got interesting again. I was hoping that the car I had would be enough to keep me at the front but judging by the pace of development I'll be at the back of the grid pretty soon!

I highly doubt you would take my place at the back of the grid

Great video once again!

Thanks everyone for the congratulations!
But congrats to everyone else to make it so incredibly close! The rate of development is insane. I think now 7 cars are faster than the Race 01 winner, and Tolo's Race 02 wonder is only 6th. I've said it before, but it really shows the quality of the competition.

I was hoping that my race 03 car would be good enough to win all the remaining races (which would give me the championship ) so I wasn't planning on developing it. But it is quite clear that if I don't, I'll be 5th or 6th again by the next race. Let's see.

I don't really know if I have massive correlation issues, apart from cooling numbers. I thought I had reached 3,2 but barely scraped in at 3,03. Have the porous media parameters been updated at any point? Maybe I'm using a too old version of MFlow?

Someone else just asked as well. I think, the biggest mistake you can make is described here:

[G-raph]

Thanks, that is very useful. I'll give it a go with a finer triangulation.

Just to be clear, can you confirm that you use the exact control surface we provide you? You don't re-triangluate it or anything like that?

[LVDH]

So, I just checked. I use a script that remeshes the monitoring surfaces with a 5mm resolution.

I just updated the page, here you can also find the results of scrutineering. A lot of teams got caught this time, even PurePower's intentions did not help:

That will explain it, then! Thanks for confirming.

What is the latest about rake?

[Koldskaal]

Hi guys. The next race will be delayed one week, so submission deadline is now Nov. 27th.

[variante]

Okok. Maybe feed us some CFD images from the previous round meanwhile. Last time they were great!

[LVDH]

Hi guys,
I have to apologize, my head was in a different world the last two weeks and MVRC was not part of it. After only realizing that there would be a race this weekend two days ago, I think the only solution was to delay it by a week.

The email is going out right now. Please make sure you have received one.

I do not know what this means for rake. It is possible that we will not have this feature this season.

I can however, provide the CFD images. This will have to wait until Monday, though. Let me know what you would like to see.

Floors

Same as last race: pressure, 3/4 view.
Cars have changed a lot. It would be nice to compare.

[G-raph]

I'd like to see the same as Race 01, Cp_tot behind the car.
