TAGGED: Discovery Live, fluids, How To, parameter

My name is Daniel, I´m an architect working as a climate engineering consultant. I started using ANSYS Discovery Live, and I have a question: do you guys know how can I use the software to measure the Flow Coefficients (Cv) values for air on specifics points for a building (represented as a box) for example? That will be very helpful for my work.

I need some more information from your side before I try to answer this one. What exactly is the formulation of the Cv that you have mentioned, with respect to external flow around a building.
Once this is known, I will be in a better position to investigate if we can do that in Discovery Live.

First of all, thanks for the quick response.
I´m very sorry, what we are actually looking for are not the Cv values, but the Pressure Coefficients (Cp) values for air. We will like to know if we can use the software to measure this results on external buildings facades.

Discovery Live cannot calculate and plot the final Cp values. But, the required pressure/velocity (freestream and at the location of interest) can be calculated using charts. These values can be exported in excel and can be further used to compute Cp analytically. Following are the broad steps required:
- Create a point at the surface of building and at any freestream location
- Add required pressure and velocity calculations
- Run the simulation and export the calculated values into excel.
- Calculate Cp analytically, using the values exported in excel.
I am attaching a small demo showing the steps to be performed in Discovery Live. Please have a look and let me know if I need to elaborate any further.
Thanks & Regards,

thank you very much for your answer, It is definitely of a great help for us. Especially the example video. I´ll start making tests with my colleagues and I will contact you soon with news.
Again, thank you
