Creating a Fluid Set

You can create a fluid set that contains fluid volume outputs and relationships between these outputs that will be used for the flow study.

Before you begin: Create a 3D shape containing volumic geometries.
  1. From the Flow study section of the action bar, click Fluid Set .
  2. Select the geometric elements.
  3. Click Join volume to join volumes that touch each other.
  4. Select the type for each fluid volume:
    • Fluid volume
    • Pipe

      To define the inner fluid for the pipe, do the following:

      1. Select a boundary edge or a face.
      2. Define the side, and select either a wet face (that is the face in contact with the fluid) or a boundary edge.

        If you select a boundary edge, you can click Other side to invert its side.

  5. Optional: To define a planar symmetry, select Symmetry as the Boundary type.

    You can click Invert side to invert the side to keep.

    When a symmetry is defined, the Fluid set information is updated in the Flow optimization assistant and shows the symmetry. Moreover, the corresponding SIMULIA symmetry feature is automatically created.

  6. Click Preview to display the computed geometry.

    If there is a contact overlap between pipes, a smooth transition is generated between them.



  7. To manage gaps between adjacent fluid elements, right-click the Elements for fluid volumes box and select Insert volumes > Create multi-sections volume.


    The feature is aggregated under the Fluid Set node in the tree. You can create as many multi-sections volumes as required. For more information, see Generative Shape Design: Creating Volumes: Creating Multi-Sections Volumes.
  8. In the tree, click the fluid set feature and do one of the following:
