cfx-meshing,examples

hi everyone

i have just started using CFX 5.4 for modeling fluid flow through pipes and constriction such as nozzels and orifices.

i have been using Ansys5.5 before, but now we have to move to CFX.

i have cople of questions, first regarding the meshing processes,i am modeling 2d and 3d pipe flow with an orifice (flow meter), what is the best way to get a regulare mesh, it is ok using free mesh, but how to build the model with regulare mesh in both cases 2d and 3d. secondely is there is a web site or other means where i can find more examples than those in the manuals.

and at last how will i calculate the vorticity through the model (with either mesh), and how to calculate the Strouhal number for the flow over cylinder(2d or 3d).

thank you regards mark
