Hi, changing the gearbox is easy, can you show where do you thing it is too large?

More about smoothing these transitions than size, per say

ok, no problem. I have modeled the gearbox around the model of a real differential (not F1, but suitable for LMPx), maybe you are right and F1 differenzial are more compact. You will find it in the next release.

To come back to this there's a couple more things around the gearbox that I think could be improved.



Here we're digging too much into the diffuser volume as a result of the low slung diff, I think just moving that up such that the drive shafts are horizonal would solve a lot of the problems, more like :

I am working on the next release: the small volume between maxiumum and minimum volume of the monocoque is imposed by the FIA rules, I will add a gap of 5mm but I would not go to far from the reference volumes.

Well, this was just an observation from my side. If those are the official rules, let's tackle them!
From my perspective, the mandatory monocoque body is too high, especially in the HANS section.
A cut like this (in orange) should work fine, in my opinion.


Removing the part marked in yellow will provide more design freedom.


Nevertheless more opinions would be helpful.

Your observation is correct, a larger gap (5mm is enough) would make modeling a bit easier and surfaces obtained by blending or sweep smooter. F1 teams have people dedicated to modeling with advanced surfaces, we don't.

Just a quick uodate befeore releasing MVRC_Volumes_R02.

The original FIA RV-CH-FRONT-MIN ruled volume, will be fully replaced by MVRC "RV-CH-FRONT-MIN-MVRC". You might find the original volume in the common files only as a reference.

This is the latest release: https://www.dropbox.com/t/2r6FWLEqfJWAn19Z

The link will be available only 5 days as usual.

I tried to include all the requests/suggestions, let me know anything you think might be improved.
Wheels are still non divided into rotating and not rotating volumes, I will do in R03.

Keep in mind that everything is a compromise between realism, the need for simulation, the need to simplify legality controls and design freedom.

As mentioned previously it would be nice to automate as much of the scrutineering as possible. So with that in mind I present to you: the autoScrutineer. Now, in order to accomodate the adoption of this tool, we have to make some small changes that I will outline below.

For the sake of transparency you can find the entire sourcecode here:
https://github.com/KoldskaalEng/autoScrutineer
The repo contains a more indepth explanation of how the script works.I strongly encourage everyone to take a look. Right now I have only implemented two different "rule-types." It would make sense to think in terms of these when we get to writing the 2025 rules.
Let’s dive into the key changes, and how they might impact you.

Submission folder structure
To check the rules, the tool needs to distinguish which .stls belong to e.g. the front wing and which belong to other parts. This requires a new submission folder structure:


What is inside a reference volume?
The script verifies if your parts fit within the reference volumes by rendering images of a scene containing both your parts and the reference volumes.

However, Z-fighting can occur in cases where two co-planar faces (like your geometry and a reference volume face) overlap. This could make some parts appear illegal. Example of Z-fighting:

So, it would be best to avoid this in your designs.

Who is supposed to maintain this thing?
For now, I’ll handle maintenance. That said, I welcome contributions from anyone interested in improving the tool.
Please note, everything is still subject to change. In the end, Andre will likely be the primary user, so his preferences will take precedence.

If you have questions or concerns then please let me know.

Thanks Christian, tomorrow I will read everything carefully, for now I say that everything seems great!
