The modelling of plasma outflows from central gravitating objects such as AGN is briefly discussed via analytic examples in the context of ideal MHD. The exact solutions are produced via a nonlinear separation of the variables in the full set of the MHD equations. Attention is given to the questions of initial acceleration and collimation of the outflow. A quantitative criterion is provided for the transition of the morphologies from highly collimated jets to non collimated winds.
