[MVRC] Mantium Virtual Racecar Challenge 2016

That is fine, there might be more to come. It looks like you are using the older release. The new one tells you that you are working with a binary stl file. But wait until tomorrow, there will be a new release (probably).

And please use the Challenge forum. It is for software issues. I do not want to abuse F1technical as a support forum for my software. Also your issue is documented and solved over there. So using it would have saved you valuable time.

I have used the forum. No reply. I knew id get a reply here so I reported it here too

OK, sorry, I was very busy the last days, but usually I check.

[Alonso Fan]

No problem

[LVDH]

OK,
I have updated MantiumWFlow. Apart from some very minor bug fixes I added an export of vtk files for easy post processing. Exporting directly into images is much more work than anticipated. And my standard Paraview scripts are not robust enough to ship out yet. I will attend the OF conference next week and tell the guys to fix it. In reality people never listen to me so lets see what happens. However now a surfaces folder in the post-processing folder is generated after the simulation. There you will find all kind of vtk files that get loaded into Paraview very quickly and will give you great benefits with post-processing.

While this may sound good, HP-Racing made a GUI for you guys!
I am not joking. After their first version I recommended a few minor improvements and they blew it up to a super cool looking software. As it only works on Windows I cannot test it myself.
This will make working with MantiumWFlow much easier for you guys and also help to make sure that you do not submit simulations with incorrectly oriented parts or with missing wheels, or whatever can happen.
I hope you enjoy and appreciate what they did.
If they are only half as good as I was with my best friend during university they will kick you asses in MVRC. With their software development they have proved that they are close.

Great news!!

Thank you HP Racing!!! =D> =D> =D>

I spent some time before the first race to learn WFlow and I now I find it easy to use (I made some test tweaking the analysis parameters just to learn how openfoam works) but a gui is a big step forward for that teams that have not done CFD yet. I think I will use the gui, but I am happy with my .bat files and the macro I prepared for PTC-Creo (I can export STLs from the parametric model just clicking a button).

Quite sure that HP is preparing another surprise.

By the way: I am overloaded with work so I decided to use the evolution of the 2015 car also for the next races and to leave the development of the new one. I will probably release as OS the CAD model of the "alternative" car, maybe someone will be inspired by that concept. The most important change is that the heat exchangers are placed forward the front wheels axle (Nissan LMP1 style).

[AratzH]

I must say, that GUI is AWESOME! This will be very helpful to avoid wrongly oriented cars and parts haha.

I'm really curious about your Nissan style car Mateo. I have a version of that myself that I am thinking of using on future races, although radiators are located in a different position (the actual rules make almost imposible to fit the cooling duct length without some ugly bends).

[etsmc]

The concept of putting the cooling in front of the front axle I think would be possible now with mantium flow. The issue with this concept before and why I did not continue with it was because I could not get the cooling requirements for 100% engine power but I believe this was a limitation of the previous solver used in the KVRC, with the new porous HX it may now work well.

if you have a look here https://mercurymotorsport.wordpress.com ... nd-2-cont/ and if the results from my testing were correct and it produced 100% engine power this car would have been only 0.68 off of CAEDevice car in the first round at Monaco.

I can't see why you guys with more experience and knowledge than myself can't make this concept work in simulation.

The principal issue is the distance imposed by the rules from inlet and outlet surfaces, and the heat exchanger surface too big.

... and with a better CoP, very good developement.

[LVDH]

You guys can be sure for the cooling inlet and outlet surfaces to disappear from now on. As there were some very innovative exhaust solutions Chris has to modify that part of the rule book as well, so it might a take a few more days before it gets published.

[etsmc]

So will the new rules be just air flow throught the heat exchanger?

Sorry about the exhaust placement.

[LVDH]

The new rules will remove the cooling inlet and outlet surfaces. Getting the air through the radiators is up to you. They only stayed as carry over and because I thought they would be useful measurement surfaces. Turns out just measuring in the box you guys submit is best.

And yes, you were one of two cars that is responsible for the adjustments in the exhaust area but I have to say it was a smart solution.

Thank you for the update. So, can I assume that cooling inlet/outlet surfaces will have a free area for the next race?

Will the pressure drop through the heat exchanger (given a flow rate) will remain unchanged?
