[MVRC] Mantium Virtual Racecar Challenge 2025 (Grand Prix Cars)

[The Rusted One]

I'm a bit shocked that I'm on the podium I genuinely thought I had too much drag with that huge sidepod inlet and with a bigger RW.
But anyway congrats to CAEDevice, that's a rapid car you've developed recently.
Also congrats to JJR for winning the championship.

[LVDH]

Many congratulations to CAEdevice! It is a great accomplishment and more or less at the home track and the JJR penalty was not needed!

Also many thanks to the team in the background as well! I was slow for reasons but they were super fast as always.

I have published the results page:

And of coarse, thank you for the nice words from JJR and Aerostar. And no need to worry, I think very few teams have started super strong into MVRC, there is simply a bit to learn to make it to the end of a race and then up to the podium-

Here you can easily see what was wrong with your cars:

When you say home track, it really is, literally, because I’m just a few kilometers away from the circuit.

Hi I have a doubt about the CAD models.

Part of what I call "floor" in my Solidworks assembly is outside the regulated volume for the floor, but it could be trimmed and regarded as part of the car body (specifically the forward area of the sidepods). The lower part of the floor (visible from below) is still fully included within the floor volume and complies with the rules against double sections, double diffusers, or channelling



Could I get a confirmation from the staff?

The post-race CFD images are missing. Is this in line with the race agenda?

[LVDH]

Nope, this is in line with me forgetting.
I will upload them tomorrow. Any wishes?

And stay tuned for tomorrow, I will also announce something you guys should like.

[LVDH]

So,
we can finally announce a Webinar from MVRC and cloudHPC.

This is great news, as you will soon all be able to use MFlow on cloudHPC, just like I do to run the race weekends.

The date will be Monday, November 3, 2025, 17:30 – 18:15.

Please let me know how many of you will be interested to join. I will use the MVRC email system to send out an email to everyone containing the meeting link, I have to confirm if it will be made public, but I assume so.

Also, as it is so close to the next race, what do you think about delaying that race a week or two, so you all have a chance to run your own simulations on cloudHPC?

I dont know if i can manage to join to the Webinar, i need to check with my boss first . Using cloudHPC sounds very good, i dont mind delaying the race.

[LVDH]

So reports are out and I have the long awaited CFD images for you:

Because I hope some of you, will try out cloudHPC after our webinar next Monday, I have delayed the next race by one week. Did you all receive the invitation?

Hello everyone!
It's been a long while since Monza. Since I haven't even finished a single race this season, I am finding some core issues in my car. Most design flaws are due to a lack of experience. So, I have been wondering about the next season and speculations regarding it. Can you please tell me what is being speculated about the next season? Like, will we have X-mode and Z-mode? Major Rule changes? Mandatory parts changes etc? What can I expect about the next season?

[LVDH]

The rules should stay very stable for next year. The new rules were one of the reasons this year was a bit rough. I am looking forward to a much smoother 2026.
Moveable front and rear wing profiles are on my list. I have not looked into how I can implement this and how much it will affect computational costs.
And that brings me to what I want to focus on during the winter break. I will put good time into tuning the simulation settings to decrease overall run times of the simulations while also maintaining good correlation with faster simulations.
Also, I am always open to everyone's input.
