But you aren’t working on 26 cars right now right? I would love to enter this competition for 26. But I have a few questions. Do you have CFD for free and is it computing locally or on cloud? Do you design model in specified CAD or is it free choice?yinlad wrote: ↑09 Mar 2025, 20:17Looks like you've been busy. You should enter! I suspect you'd need to develop a new car to meet the mvrc rules, particularly about surface thickness but the more the merrier!janci_kp wrote: ↑08 Mar 2025, 22:53Hi guys,
my friend just told me about this competition and I would love to share my 2026 car that I have been developing since the new year. Here is the pressure distribution and you can find many more details on my X page

Hi, the CFD solver is OpenFOAM, the pre/post processing is done with a free version of MantiumFLOW (https://mantiumflow.com/). The official CAD format for the car submission is STL, in case the staff decided to change it would be STEP (with standardized STL conversion) so you can use any CAD software to produce your models.janci_kp wrote: ↑10 Mar 2025, 10:53But you aren’t working on 26 cars right now right?

Yes, MVRC2025 is using the 2026 F1 regulations. We try to stay 1 year ahead of the real cars. https://mantiumchallenge.com/ has everything you need to get started.
+1 from my side. Still far away from the first run.spacehead3 wrote: ↑06 Mar 2025, 16:24Can't resist a little teaser. First run is in the books.

99% likely not the solution but make sure all the file names don't have dashes "-", which is actually in all of the mandatory parts when I downloaded it.Coventry wrote: ↑09 Mar 2025, 21:43Hey, I’m currently trying to get my feet wet with mantiumflow before jumping into this challenge, I’m stuck at building a case. The loading geometry panel gets to 95% and then doesn’t move from there, I left it over night but no progress. I’m just trying to run the car tutorial off the site, I’ve tried building on both the competition and demo versions of mflow but get the same result with both. Does any one know where I might be going wrong?
When looking at the new mandatory parts, I did wonder why we switched from underscores to dashes, but did not think much about it. MFlow probably complains, because OpenFOAM later does not like this at some step.The Rusted One wrote: ↑14 Mar 2025, 09:3799% likely not the solution but make sure all the file names don't have dashes "-", which is actually in all of the mandatory parts when I downloaded it.Coventry wrote: ↑09 Mar 2025, 21:43Hey, I’m currently trying to get my feet wet with mantiumflow before jumping into this challenge, I’m stuck at building a case.

common mistake
Thanks for the hard work. Looking forward to getting started in earnest. Could you clarify if the regulations are final at this stage? If we will take on Appendix 2 from the proposed regulations or use the inlet as per last year.
This is my interpretation of the rules about the engine inlet.yinlad wrote: ↑18 Mar 2025, 00:33Thanks for the hard work. Looking forward to getting started in earnest.

I just worry that with no mandatory plenum and no requirement to model one to deliver air to the engine inlet surface, engine covers could quickly stray from a 'reasonable' shape/function
This is what I understood but it seems Andre does not want to use this implementation.CAEdevice wrote: ↑18 Mar 2025, 13:09This is my interpretation of the rules about the engine inlet.yinlad wrote: ↑18 Mar 2025, 00:33Thanks for the hard work.

To avoid confusion, I would add to the rules: all the air that feeds the engine must come from a flow through the inlet of the airscope (which by regulation is located all above the helmet).
