Streamlines for a RhoPimpleFoam Simulation
 

I am trying to simulate the rarefied gas flow through a microchannel using rhoPimpleFoam over a pressure gradient. I ran the simulation for the conditions as mentioned in the working case directory attached and got the velocity and pressure plots. However I am unable to use any of the filters such as plot over line or stream tracer to visualize the results further. As I am new to OpenFoam I am not sure as to how to proceed. Please help me out..

The working directory can be downloaded from here

Many Thanks
