Constant value of velocity/pressure across entire domain

#1 · March 30, 2026, 2:43 pm

Hello there,

I am having an issue where all of my simulations show the same velocity magnitude across the entire domain. This is the same for all models regardless of geometry or settings. Even attempts at streamlines end up with lines that just stop after reaching an obstacle. I have attached some pictures for reference; the attached pictures are from converged solutions of two tutorials that I have followed step-by-step, namely the DrivAer tutorial (https://baramcfd.org/en/tutorials-en/tutorial-baramflow-en/tutorial-flow-drivaer-en/) and the High Speed Train tutorial (https://baramcfd.org/en/tutorials-en/tutorial-baramflow-en/tutorial-flow-train-en/).
This same problem is also occuring in my own case which is shown in the fourth picture (cross section of a building).

Any help would be much appreciated.

It appears that the initial conditions are being displayed because the “Time” value in Paraview is 0. Click the right arrow inside the red circle in the image below to view the final result.

I didn't know I had to do that for steady-state simulations as well. Thanks for letting me know!
