TAGGED: Discovery Live, Fluid Volume, fluids
July 3, 2018 at 5:08 pmpeter.trethawaySubscriber
How does one select a cross section of a fluid volume for a probe measurement in internal fluid flow analysis in Discovery Live?
I understand how to select an inlet and outlet face, but can I select a cross section to be a face?
Also, is it possible to plot a value through a cross section across a length (pressure variation throughout a pipe diameter)?

For a probe measurement at a cross-section, you can create a plane at that cross-section and take the probe measurement at that region. (refer picture) 2. Probe measurement can be taken at any face/plane as mentioned in above point. 3. This feature is currently not possible in Discovery Live, We thank you for sharing your feedback. We will share your idea/input with the product development team.

I also found that one can use the split bodies tool to create a probe face

Split bodies does not seem to work in internal flow analysis though.

I would also like this feature to be available in internal flow analysis.
November 23, 2018 at 9:10 amSubashni RavichandranAnsys EmployeeLukePJCP Splitting flow volume in internal flow analysis is not possible. To create a probe on a required plane the best solution would be to create a plane and then select a probe on it. We thank you for sharing your feedback. We will share your idea/input with the product development team.
November 28, 2018 at 3:08 pmlukeSubscriberSubashni I split the model up using planes and the "split by plane" feature until I got the section I wanted, then added all the split bodies to the simulation by right clicking them on the structure tree. This seems to still allow the simulation to work. Although, I have a system whereby there is a 330 L/m input and when I measure the flow rate on the section as shown in my screenshot, I get somewhere around 28 L/m in that section which cannot be correct and should be somewhere near 330 L/m. What do you think of the method and should it work?

Is it possible for you to share the model with us so that we can get a better understanding? I can send you an Ansys Secure Transfer link to transfer your file in a secure way.

I received your model and I'm looking into it. I will get back to you as soon as I figure out the solution.
November 30, 2018 at 2:47 pmSubashni RavichandranAnsys EmployeeLukePJCP We simplified the problem to a pipe and measured the flow rate on a plane and on the face (like in your example). We observed that the result on the plane seems correct and the one on the face seems wrong. Refer attached model and picture. We will consult the development team on this and let you know of the reason for this disparity. The best practice would be to measure the result on a plane although for your particular case that wouldn't work.🛈 This post originally contained file attachments which have been removed in compliance with the updated Ansys Learning Forum Terms & Conditions

Subashni I thought as much.
Thank you very much for helping out, I'm limited with planes a little so I would appreciate a section probe feature in future releases.
