[MVRC] Mantium Virtual Racecar Challenge 2017

[CAEdevice]

Hi, depending on the new rules (expecially about Chris' exertion during the rule check and about the "intro class" ) as soon as some data will be available, I could a start a promotional activity, addressed espcially to professional engineering services providers and motorport "advanced" fans in Italy. Would it make sense to have a larger number of teams?

Sounds cool, while I do not know how to manage the workload, I do want more teams. I am now working on the new software. As soon as that is done, we can get into promotion. The new rules I have come up with are minor and mainly cause work for me, so I guess Chris and Richard should be fine with them. Maybe we will know more next week.

Any idea what could be causing this? The mesh looks fine as far as I can see:

Create time

Create mesh for time = 0

Read mesh in = 0.19 s

Dev2018_v36...

I am still at Dev2017_v2

I'm using Fusion 360 and it versions each and every save, it's actually the 3rd run

I see. Honestly I have to say that although I have not simulated a 2018 car, I am doing a lot of "mental" CFD and 2017 post processing.

PS: maybe you renamed/moved the working directory after running Mflow but before launching the runcase.sh command?

Got it, happened before, STL names starting with numbers.

I can't wait and see if there is the possibility to rotate the heat exchangers in any diretction or at least in two alternative directions.

I have found this on YouTube (thanks to Gary Paterson who is working on the AssettoCorsa model of my 2017 car).



I hope this is useful to kill the time.

Meanwhile, I was looking at the heat exchangers of LMP1-LMP2 and F1 cars. I have the suspect that our hx have a slightly lower pressure/energy drop and that the required flow rate is a bit overestimated.

This is going to be awesome to drive!

Would Gary mind if, when I have some spare time, I could make a Porsche 919 sound for it?

I tested it at an earlier development stage: the original tyres and suspension angles (with MVRC dimensions and specs) made the car difficult to drive. Meanwhile Gary did a very good tuning job, introducing a more detailed tyre simulation model and now the car improved very much. I hope it will be released soon.

It will be be an open source project once released, so any improvement will be welcome.

It is awesome to drive, IMO much preferable to the LMP1's as its RWD with a lot less interference and things to manage with regards to the hybrid system. A lot more 'pure' of a driving experience in a sense.

As for SFX - please do! There are plenty of us model makers and guys who do physics, but there is always a shortage of SFX guys, so if anyone wants to dip into the Sound making stuff then we would love that!

Its quite easy to drive for now, as the aero is very stable (almost static right now). Once Jackson finishes the aero files based on your CFD that respond to height/AOA/yaw etc, I think it will become much trickier (and of course realistic) to drive, with the added challenge of trying to find a setup that gives a stable aero platform.

Can't wait to get to that stage, hopefully not too long!

Also looking forward to following everyone's progress again this season, really enjoyed it in 2017, keen to see how everyone evolves

That's great! I won't be able to lend my services straight away though because of university work but maybe in a month or two

That video is seriously cool...

The required flow rate through the heat exchanger depends on the design of the heat exchangers... maybe ours aren't so efficient, so you need more air flow?!

On a more serious note: Andre and I have been discussing this very aspect recently, so there might be some tweaks to the heat exchanger parameters for 2018....
