You can add additional non-background fluids to the section definition by clicking Add Species.
  4. Select the fluid domain by clicking the glyph in the model.
  5. Specify the Background material by clicking and searching for an appropriate material from the top bar.
  6. Specify the second Material definition by clicking , then repeat the search process from the top bar. You can also add additional materials to the section definition by clicking and navigating to the new material you want to add.

    Note: To delete one of the species from the section definition, click next to its row in the dialog box.
