we are simulating a pump using ANSYS CFX ...
We need to generate streamlines, starting at center of each element on the inlet and export the data out. Therefore, if we have n elements on the inlet, n number of streamlines need to be generated. Then, we need to trace each streamline separately and export the relevant information (i.e, pressure, velocity, or any other user defined variable) out for further analysis.
We already created the streamlines at the center of each cell on the inlet in CFD-Post. Then, we exported the streamlines information out as .csv file. However, when we open the file in excel, it is impossible to see which points (nodes) are related to which streamline. We need to be able to distinguish the streamlines from each other.
In another word, we need an excel file, which has a format similar to the following:
Streamline 1
x y z variable1 variable 2 ...... variable m
(number of rows here depends on the number of nodes forming this particular streamline)
Streamline 2
x y z variable1 variable 2 ...... variable m
(number of rows here depends on the number of nodes forming this particular streamline)
.
.
.
.
up to the n-th streamline.
Hello!
Sorry that this is not a answer to this question.
We have faced the same problem: we want to calculate the relative parameters and do not know how to separate the streamlines.
Have you got any anwers to this question?
If you have solved it, would you please kindly share some of you experiece with us?
yes, I have found a way to export the 3D lines data separately. The way I do it is the following: - generate the 3D streamlines. - make sure to remove or extend the limitations of the streamlines - go to export data and select "export data from streamlines". - select the wanted quantities. Make sure to include the streamline number and the time on the streamlines if necessary. - click on export Ps: the exported data may be disordered, so they may need to be processed.
Thank you so much for your detailed answer!! I'm going to try this with your method. Really thanks for your kind sharing, it's helping me a lot!
