plot water height = f(time)Hello,
I made a simulation of free surface flow of water in a canal (in transient study ) and in post-processing i want to plot the water height according to time on the point defined by the intersection between line 1 and the isosurface in the canal (See Attachment). - It was easy if we could create a point by intersection between line and isosurface!! I do not see how I can do that knowing that I have not the height of water but I have the water volume fraction. Thank you for helping me |

You need to use a bit of lateral thinking.....
Generate a line from the bottom to the top of the domain at the location you wish to measure depth. Then do a line integral of water volume fraction. And there you have the water depth. |

Thank you
but how can i do the line integral of water volume fraction ? There is not the line integral function in CFX POST |

Thank you it work
