Mapping the fields values to your car surface is failing. This indeed only happens sometimes and is an OpenFOAM issue. This can be because your mesh is too big (open geometry) but more likely because of bad cells somewhere on the car. There is not that much you can do about it. You could try to locate where you have big pressure gradients on you car surface in Paraview to possibly detect where the issue is and fix the geometry. Maybe checkMesh tells you something. You could also try to change the distance slightly in the sampleDict. There are many options, if you really want to fix this I could point out some more options but you would basically have to rerun the entire simulation, as it is pretty much a mesh issue.

I did run two more cases, one with old car and one with new. In both cases sampling has failed.
That's something unexpected on top of not working new car actually.
It only gives out the CpT files, and for some reason crashes for the rest.

I checked the mesh and weird values, but nothing unusual.

Edit:
When disabled CpT, Cp actually has managed to process... looking more into that

Hi all,

Is there a posibility to work in Fusion 360 for this?

You should be able to use any CAD you have/know.

You can send me your case, I can also compare it against an old version of MFlow.

I just sent out the reminder for the first race. You should all receive an email in the next few minutes. However, I have noticed that the contact list is a bit shorter than it should be. When you guys sign up for the championship, you receive an email where you have to confirm that you are fine with receiving MVRC emails. If you really do not want them, then that is fine with me, just keep in mind that the emails contain the link to submit your cars. In case you have changed your mind and would like to receive the emails, just sign up once more and make sure to go through the cool double opt-in process, some cool people in the EU want us all to follow.
Anyway, good luck to everyone. I see you are all struggling with the car development. With all the new teams, it will be interesting to see if any of the new ones find their way to the top.

I haven't received the email... I thought that I had joined the newsletter.
Anyway I signed up again.

Our team name is GCBB corse. Hopefully now it's working

Hi! Neither I... I signed up again too with the same team name, you can also delete the older account.. however I realized that I received only the email to set my password, and then I didn't receive no more mails..

Can I send my email address in order to let you add manually maybe?

thanks in advance...

I didn't get an email either but have signed up again just in case

Thanks for that. I will let you know about sending the case. Theoretically I've found workaround for development purposes - takes bit more time and gives only CpT and Cp, but I can handle it as long as it will work for each case.

I'm using Fusion 360 and if i remember correctly Koldskaal also uses F360.

For this season I'm also using Fusion 360. Before that I was using solidworks. The T-spline modelling is quite powerful and allows for very nice flowing surfaces, once you get the gist of it.

I don't see that I ever got this email, I just signed up again so I'll see if it works this time...

I also didn't receive the email, going to register again

I have to manually send the email to the newly registered teams again, which I will do later today. So no need for you to sign up multiple times. If you go through the double opt-in process, your email is in the list for the automatic emails from that point on.
Even if I miss one of you, there will be another one next Saturday.
