ust only produce only continuous closed sections with all parts of the section either visibly from above or below.
12.4 When intersected with any Y-plane, it must only produce only continuous closed sections with all parts of the section either visibly from above or below

12.5 After these requirements are met, additional parts may be added to the volume inside of the volume RV_FLOOR_FENCE_V01:
12.5.1 Up to four fences are permitted per side of the car.
12.5.2 The fences must be a part extruded purely in Z-direction.
12.5.3 The fences have to be a separate part.
12.5.4 The fences must have a constant thickness of 10mm

Hi the Linux release looks OK, the symmetry plane is in the right place and also the vertical alignment is ok.

that's interesting. I wonder if the alignment issue is Windows specific in that case. I even got the new reg files and exported the wheels to test, but they are still floating above the floor in mflow

I did not update wheels and suspensions, maybe it depends on this.

Nah my entire car is 275mm off the floor, I tried the latest files to check if it was perhaps something in an older version of the regs, but it's still the same for me

It seems to be approximately 260mm off the ground. I've moved the wheels down 260mm and they seem to be at the same level as the wind tunnel floor but I can't be certain it's exactly correct

EDIT:

Checking the reg files I'm seeing things are 275mm in Z

Setting this to 0 puts the wheels approximately 15mm through the WT floor, not sure if that's intentional for sealing etc. But I don't know if the mflow windtunnel is wrong or the regulation files are wrong

I think at this point if we could move the wind tunnel up to match the files that'd be easier than having to go through and transform every part we've made against the reg files.

Hi,

Sorry for being dumb, but where can I find this latest Windows version of MFLow? I have registered my team but nothing appears in the Windows download section on the website.

Thanks for your help!

Oh, my poor, non-existent testing is not only because of my lack of time but also I do not have a new car, developed by the new rules. Please someone send me a car, so I can run it. Many thanks.

I agree. You can pretty easily fix this yourself in the meantime. After building the case go into system/blockMeshDict and edit the z coord of the first 4 vertices to -0.04 (adding the 0.275m)
then go into the "0" folder and edit the file "U". Find the front and rear wheels and edit the z-coord of the origin to 0.275

Save the changes and run the case like you would normally

OK I don't know why but it seems that my car has issues with the Y direction as well

The version of the Mflow is downloaded today, and the STL files are from .... 1st of july V5
