Yes, the car looks fantastic.

That looks awesome. Is that the 'PPR Technology Centre'?
Jokes aside, it's a beautiful render. Water could be a little less 'blue' but that can be overlooked

Presumably the "blue" is a result of the colour that the inside of the pool is painted, as opposed to any sort of reflection of the sky...? So it could realistically be yellow, purple or any other colour the owner wanted?
Anyway... a little render of the CCE LMP01 in round 1 configuration (actually, it has the "old" engine intakes... so its not quite "right")...

On second thoughts, machin is correct.

Sorry about not having taken up on your earlier query on this. To extract the pressure differential, please do the following:
- Start ParaView;
- Open the openFoam file;
- Only select the boundary condition (in the part option) that you want to calculate the surface integral of pressure on;
- Apply a calculator filter;
- Set a new field "Pressure = 1.2 * p" (the pressure calculated and output by openFoam is normalised by the density);
- Apply the Surface Integral Filter;
- the surface integral of pressure is reported under Pressure.
Change the selected boundary condition to extract the value at the other surface.

You can, but it just takes longer to establish, hence more iterations...

Please send the STEP format. I am sure that Chris will appreciate having something easier to handle. On the downside, this removes the control of the STL export from you.

The new KVRC background.... Great rendering! Very impressive.

Thank you!!!
Yes, the preliminary run saves some time, but I would need the list of the commands /procedures to run.

I am not going to get my car done in time.
I've barely drawn the side view and not even touched the rear wing yet. I only just finished the comprehensive article on end plates just now.
I will crack on tomorrow but I will doubt I will have it finished.

My car is almost complete: I have already submitted it, but I hope to obtain some other front downforce in the next hours.

Its my private mansion

The source of the water color is as machin said the color of the pool.
