correct visualization of multiphase flow
 

my flow problem involves a polymer flow into a honeycomb like domain. i use a multiphase flow with polymer flowing into air and permeability was assigned accordingly.

i'm not sure what is the correct way to 3D visualize my polymer flow. currently i'm using isosurface but isosurface requires a value and my value now is arbitary.

is there a proper way to visualize my results? txs
