Would Symscape be able to give a tutorial on how to simulate pressure and stream lines on an F1 in Schools car?
I will assume you are familiar with the tutorial "Flow Over a CO2 Dragster". This simulation solves for pressure as part of the solution procedure.
To see the pressure field drag and drop the Scalar Fields->p tool in the Results Tool Palette onto the the geometry where you want to see pressure, just as the tutorial does with velocity. For more details see "Using Fields and Variables".
To create streamlines, first you need to create a geometry source (e.g., rectangle) as in the section "View Particles Tracks Through the Volume" in the tutorial "Incompressible Flow Through a Pipe into a Box". For more details see "Particles or Streamlines".
