Hi guys, i'm fairly new to Flow sim (using solidworks 2015) and i am facing a problem with displaying results.

I have a shower head dispersing gases towards a substrate, and I want to optimise the distance between those two elements.

First I was thinking i could simulate the flow and then display the density and pressures on planes parallel to the shower head, but apparently, there is no way I can place a surface plot on a plane.

I tried to place a solid part facing the shower head (assembly level)  and place a surface plot on it, but nothing showed up on the surface. Same result if I run a simulation on the shower head at part level, with a feature mimicking the substrate.

What am I doing wrong? Is there a way to visualise fluid density on a plane? Or on a graph (pressure vs. distance from center)?

Thanks, people.
