Re the floor : "when cut by any Z-plane in the interval Z = (35mm, 275mm) produce up to two sections."

Could someone clarify if this per side or across the entire floor, and what the intent of the rule is? Because with how far down the diffuser fences come you run into 3 sections between the floor boat and diffuser walls by default, rather than through some effort to exploit something.

From my understanding, that rule is only aimed at the floor body, so its two sections not including the floor fence.

Yeah I know, the point stands that you can end up with 3 sections made up of diffuser walls and floor boat, 5 sections if you included diffuser fences. Unless its per half car instead of per full car.



This is what I mean. If that is how it is, that's ok. I just wanted to get clarification so I know if I need to manage the overlap between the floor ramp under the gearbox and the 15mm of protruding diffuser wall we get

It's a bit off topic but need to ask. I installed ubuntu on one of my drivers for mvrc stuff but i could not manage to open my case on mflow. Therefore i cannot create the case file and start the simulation. Do i need additional things to install before using mflow on ubuntu?

I'm seeing the bottom of the diffuser walls even with the 35mm plane, so there is no intersection between those surfaces.

Not sure I follow. This is a slice of a floor at Z = 45, due to the diffuser I have 3 sections within a region of Z that the maximum allowed is 2.

Ah, yeah you're right

The rules always apply to the whole car, unless explicitly stated otherwise.
The diffuser fences are not included in this rule.

Regarding the three Z-sections of the floor: I think this is just an oversight from adapting the f1 rules to mvrc. In the f1 rules the diffuser-sidewalls are treated as seperate parts. So they wouldn't contribute to the number of Z-sections of the floor-body. The sidewall has its own rules:



Perhaps it was a mistake to merge with the sidewall with the floor-body. What do you guys think? should we make the number of sections rule only apply above Z=50mm? or more realistically make the diffuser sidewall a seperate part with its own rules?
