how to measure the wave height over time by freecad

Hi i have a question .. I want to measure the height of the water surface over time in a regular wave example , but when i use measure tool in freecad , The height result is always equal to the height of the point which I set. so how can i get the results?

thank you


  • Hi,

    Measuretool works fine for me. Can you share your "point" parameters ?

  • thank you for your reply

    my water tank's length is 7.5m, width is 2.5m, height is 2m, water height is 1.0m;

    piston's length is 10mm, width is 2.5m,height is 1.5m;

    the motion of piston is "regular wave generator (piston)",wave order is "2nd order",depth is 0.4m, wave height is 0.1m,

    I refer to the official tutorial "how to set up and run :casewaves";

    the "list of points" in the measuretool is"2.5, 1.25, 1.0",the result height is all equal to1.0,

    the"grid of pionts" is "1.0, 1.25, 0.1; 0.0, 0.0, 0.02; 1.0, 1.0 20.0",the result height is all equal to 0.48,

  • Hi again,

    for the "2.5 1.25 1.0", you should provide a grid also, something like

    2.5 1.25 1.0

    0 0 0.02

    1 1 100

    for the second example you provide, for the Z parameter you have: start at 0.1, every 0.02, 20 times

    and it gives you 0.48, I think it is normal. It means that the true water level is higher (0.48 = 0.1 + 0.02*(20-1), it gives you the highest point of the evaluation


  • oh, thank you my bro ,i got it

    best regards to you
