TAGGED: Discovery Live, fluids
January 29, 2021 at 11:48 pmsinaSubscriber
I am running an internal flow simulation. I sketch a point on a surface, define a prob, and read the flow velocity in all three directions (Components of X, Y, and Z separately in the flow velocity prob). Shouldn't the velocity of flow in a direction normal to the surface be zero? Surprisingly it is not.

Hello Sina Amini Niaki
I suspect this query is related to Discovery Live but can you confirm the product that you are using?
Did you check the velocity contours near that location? Are they showing reasonable results?
Can you share some snapshots of the probe location and its results?
February 1, 2021 at 5:41 pmsinaSubscriberNaresh Patre Thanks Naresh. I use Discovery Live and I am doing an internal flow analysis. I have attached a snapshot. As you see the probe point is not in the flow. But, the numbers in the graph for its velocities (in X and Y directions) are not zero which is surprising to me. That's why I am suspecting all numbers I read for flow velocity even when it is inside the flow.
February 2, 2021 at 8:59 amNaresh PatreAnsys EmployeeHello Sina Amini Niaki I did a quick test and couldn't reproduce the issue that you are seeing. See below snapshot. I created one point outside the pipe and then another inside the flow domain. As expected, the former location reported zero velocity . I would suggest checking at some location within the flow domain and compare the values with other result types (like contours). If you are seeing any significant difference, please share the model for further investigation.
