Hi all,

I have attached an image of my reactingTwoPhaseEulerFoam simulation, where you can see that the velocity at wall cells becomes extremely high, whereas the velocity at the inlet (top face) stays lower and gets not nearly up to the velocity at the wall.

This happens when using noSlip and when using slip BCs and also not in all of these channels from the screenshot, of which there are six.

My p_rgh boundary condition for the inlet is prghPressure, 6 bar, all walls are zeroGradient.

The U boundary conditions for inlet are pressureInletVelocity, walls are all noSlip.

Do you think this has to do with mesh generation? In a simple case, it all runs well.

Best regards,
Vinz
