    OK so I got this result below and I am wondering how to calculate the pressure field from density?

    There is a functor which directly computes the phys. pressure in si units for you, have a look at our many other examples in OpenLB. Further, it would be nice if you could share a video from you simulation with the community.. the pictues looking nice.

    Here is an animation from some time ago – this one was (I think) 2D by the look of it.
    Also just using bounce-back in this case, which can be seen by the low wall velocity.

    Here is the full 3D animation of the Ferrari Dino case (just using bounce-back).
    It was 100 million cells, ran on runpod GPU for 50k iterations, took 42 minutes.
