Coupled non linear first order equation [message #92867]

I have a system of (momentum) equations in cylindrical coordinates:
(r,theta,phi)

rho*(dv/dt+(v.del)v=A(r,theta,phi)
where the velocity v(r,theta,phi) and A are vectors and dv/dt is the partial derivative wrt time. del is the gradient.

I am trying to find the steady state solution to the equation
(v.del)v=A.

I have tried different simple methods but nothing converges. Any suggestions .

Thanks
Jay
