Simulation results

After the simulation was complete, the following values were shown and I don’t understand why the solver shows equal pressure everywhere in the simulation.

the pressure around the car is the same everywhere

It’s the same with speed

What can be done to reach realistic values?

Hi dani_marciu
thanks for reaching out to us in the forum.

One thing, I noticed when looking at your simulation is the range of the scalar.
The range is from 0 m/s to 2633 m/s. This indicates that we might have a small cell with unrealistic high-velocity values.

I have created an Iso Volume which indicates that the region of the high velocity cells are at the top edge of the diffuser inlet.

Looking at this closely I noticed this small face which might have led to the bad mesh.
Please try to clean up this area to make the edge only three nice faces.

Best regards
Sebastian
