Dear all
I have question in the catalytic converter tutorial. In the Global initialization tab they have introduced w= -2.8 m/s. Why in the tutorial the negative sign has been introduced instead of 2.8 m/s? I Need your help Thank you |

Because the flow is in the negative w direction. Isn't that obvious?

When you define velocity at an inlet you just specify the magnitude. But for the initial condition you specify the full velocity vector. Hence the initial conditions is w=-2.8m/s, but the inlet is as positive number.
