For visualizing the bounding boxes, you'll have to convert the boxes from. [cx, cy, cz, rot_z, length, width, height] to an array of points that represent the 8 corners of the box. You can use a function like this, that takes an array containing [x,y,z,h,w,l,r], and returns an [8, 3] matrix that represents the [x, y, z] for each 8 ...

The PIMPLE algorithm combines the PISO with the SIMPLE. That means, the problem is transient but we use the SIMPLE (steady-state) treatment to find the steady-state solution for each time step. This allows us to increase the Courant number larger than one. irts toulon
