The browser view of a Solid is shown below:
Note that the Reference Fluid appears as an input. This input is automatically linked to the Reference Fluid (or the nearest clone of the Reference Fluid) when the Solid is created. This link cannot be changed using the Link Cursor, and is displayed for information purposes only.
The other inputs to the Solid can be specified as links. The Available Porosities and Partition Coefficients are vectors (by element), and hence can be expanded:
A Solid has a single output (and hence has the same ID as the medium). The Solid output expands to reveal the medium properties, as shown below:
The Available Porosities and Partition Coefficients outputs are vectors. You can create a link from the entire vector, or expand the output and create a link from an item of the vector.
That is, each of the properties that you enter for a Solid are "passed through" the element and become outputs which you can then link to other elements.
You can save these results by clicking Final Values and/or Time Histories in the editing dialog for the Solid. Checking one of these causes all outputs to be saved as results. If you wish to save only one or several of these as results, you can use the context menu of the output (accessed via a right-click) in the browser to turn on or off one or more of the outputs. In this case, the checkbox in the editing dialog would become gray (indicating that some of the results will be saved).
