Now I calculate the verification of collidingBubbles3d.
I 'd like to ask a question.
I want to verify the Laplace law and it needs sigma, radius and pressure difference.
But How can I consider the pressure.
In the code :around 344 we can substitute the number and that is pressure1
Then we can get *g value but I couldn’t distinguish the pressure2
as for the collidingBubbles,Could you help or suggest the way of verification to calculate laplace’s law.

Hi all,
I saw the program in palabos below.
may be I can use it?
I bothered school discussion about using palabos.
Could you help me anyone?
class PressureGradient {
public:
PressureGradient(T deltaP_, plint nx_) : deltaP(deltaP_), nx(nx_)
{ }
void operator() (plint iX, plint iY, plint iZ, T& density, Array<T,3>& velocity) const
{
velocity.resetToZero();
density = 1. - deltaP*DESCRIPTOR::invCs2 / (T)(nx-1) * (T)iX;
}
private:
T deltaP;
plint nx;
};

Hi all
I made a lot of mistake like above
I can compute the pressure in the collidingBubbles3d.
and next I’d like to know how to make the profile that in a box there is a sphere and
everything except the sphere ’ s pressure is constant.
could you help me anyone?
Thanks you for the post.
Hi guys, Im a newbie. Nice to join this forum.

Hi R1zbear and all,
my problem was solved.
in order to get the pressure diffference,I used the p1->(x,y,z)
and setToFunction
you just check the value of pressure.
it may be easy but not easy for me.
