Streamlines

Import a .h5 file from a HyperWorks CFD application into Inspire Studio, where you can then edit and visualize streamlines as static images or animations.

  1. Open the .h5 file.
  2. In the Model Browser, select one or more streamlines.
  3. On the ribbon, click the Analysis tab.
  4. Click the Streamlines icon.
    Note: If you selected multiple streamlines, you will be asked if you want to unify their parameters. Selecting Yes would apply the parameters of the first selected streamline to the other streamlines in the selection.
  5. In the Model Browser, double-click the selected streamlines to edit them. In the Control Panel, you have the following options:
    Option Description
    Time Range Define the time range using the slider or by entering a start time and an end time. To visualize a shorter portion of the streamline, reduce the end time.
    Streamline Range Define the first and last streamlines to visualize using the slider or by entering the number of the first the last streamlines you want to see.
    One streamline every Define the density of streamlines displayed. For example, if you enter 10, every 10 streamlines are displayed.
    Diameter Define the diameter of each streamline, which is rendered as a tube.
    Display as:
    • Color Map: Use a color legend to visualize the streamlines. This is a static visualization; you can zoom in and out to inspect the streamlines as desired.
    • Stream: Visualize streamlines with embedded animation.
      1. You can change the color and texture of the streamlines at the bottom of the Control Panel using the Streamline options.
      2. To play the animation, in the View Controls, click Animate Objects .
    Color Map Use the slider to concentrate on certain velocities. For example, if you want to study what happens around 22 m/s, reduce the range to that area.

    Transparency: Currently only works for rendering. Adjust how you want to render streamlines.

    Channel: Select a data type to visualize.

    Streamline Color: To define the color, choose from the following options:
    • Select a color.
    • Select an image, a .png that is 1 pixel in height and 100–1000 pixels in width. If you want transparency, use a .png with alpha. The image is 1D and mapped onto the streamline tubes.

      The image overrides the color.

    • To blend the color with the image, click the plus symbol (+). You can tell if the blend option is turned on by looking at the image preview.
    Tail length (%): Define the length of the image as a percentage of the entire length of the streamline. The image is repeated from left to right, with a gap in between ("wave"), to cover the length of the streamline.

    Wave length (%): Define the length of the gaps in between the repeated images as a percentage of the entire length of the streamline.

    Speed ratio (%): Define the speed of the waves as a percentage of the actual speed. For example, enter 10% to obtain 1/10th of the actual speed.

  6. Right-click and mouse through the check mark to exit, or double-right-click.
