Plotting velocity at specific point

S1m0n1 · February 19, 2013, 13:38

Hi. I'm trying to plot the velocity at a specific point in a 3D room, i.e. (x,y,z)=(1,2,1). I'm trying to do this so I can determine when the problem becomes mesh independent. Thanks.

You will have to create a point at the location, and then create a monitor at that point and assign the velocity to that monitor.
You can then choose to only print the monitor info or print and write.

Luke is absolutely right.

Tyr it in that way.
It will work.

Thanks to both of you for replying.

I'm not sure what you mean by "create a point." Do I have to go back into DesignModeler to create it or can I do that in Fluent?

Ok, I figured out how to do the monitor but I can only do it for the whole volume. Can you help me with creating a point to monitor?

Ok, so I created two points in my volume. One I put in the middle and one I put in front of the inlet so that I could see if it was actually working. Both I have set to Flow rate, velocity, velocity magnitude. I've done a number of iterations and they both show no mass flow.

What I'm trying to do is see the velocity through a point in the to see when the solution has converged. Can someone help me out?
