Hey,
I assume you’re trying to plot velocity against height in the y-direction, right? As far as I know, this is not possible with the current post processing features from SimScale. You can, however, use further post processing softwares, such as ParaView (free software), to do this. You can probably find some articles on forums about how to upload your SimScale results to ParaView .
This specific feature that you’re talking about is called Plot Over Line on ParaView . Here’s a tutorial if you’re so inclined to test it yourself: Beginning Plotting - KitwarePublic
I uploaded your results to ParaView and plotted All speed versus Y along the middle line at the outlet. This is what it looks like:
