Hello，all

I’ve been watching ShanChenForcedPostProcessor2D recently, and I don’t quite understand the following line of code：

rhoField[0][cell.getCellId()] = cell.computeRho()*rho0[0]

What density is calculated by this density field, and why is the multiplication of two densities？

Thanks

It scales the desity to e.g. physical units while the computation always uses lattice units where who is scaled to rho.

Sorry, I don’t quite understand the meaning of scaling density. Could you explain it in more detail？

Hello，all

I have a few code in ShanChenForcedPostProcessor2D that I don’t understand very much.

util::intersect ( x0, x1, y0, y1,
x0_, x1_, y0_, y1_,
newX0, newX1, newY0, newY1）

What are the functions of these codes，and What do x0 and other symbols mean？
Thanks

util::intersect computes the intersection between cuboids (x0,x1)x(y0,y1) and (x0_,x1_)x(y0_,y1_).

Thank you very much for your reply.Where do the values of the eight parameters come from? I can’t find out where to assign values to these parameters. In addition, do you mean two sets of lattices by two cuboids?
