Dear all,

I had two questions about CFX transient simulation.

First one, how can we superimpose the profile of a certain variable (such as velocity u, v or w function of another variable such as z coordinate ) from different trn files (at different time) into a single chart viewer in the post-cfx, in order to make a good comparison of the velocity variable in the time dependent process please?

Second one, suppose we got a velocity u profile at a certain location(a polyline) in the chart viewer, assuming there is fluid moving outwards (along x+ direction), and also fluid moving inwards (along x- direction), according to the mass conservation, the former should equal with the latter, but in this very case, how can we check mass conservation according to the chart viewer please ? Is there any tool in CFX post that we can use to verify please?

Thank you very much in advance.
