rho
(float)fluid density
mu
(float)fluid viscosity
b1
(float)body body acceleration in x direction
b2
(float)body body acceleration in y direction
b3
(float)body body acceleration in z direction (required for 3D)
thickness
(float)element thickness (required for 2D)
kappa
(float)fluid bulk modulus (optional)
