Algorithm 2

Constant density Constraint (calculation flow of the constant density constraint solver).

(1)	while:
(2)	for i in particles:
(3)	compute intermediate density:
(4)	compute density constraint:
(5)	compute Lagrange multipliers: and
(6)	compute position correction:
(7)	for i in particles:
(8)	update position:
