Gets the value of the solid property.

<p>
This accessor method returns a reference to the live list,
not a snapshot. Therefore any modification you make to the
returned list will be present inside the JAXB object.
This is why there is not a <CODE>set</CODE> method for the solid property.

<p>
For example, to add a new item, do as follows:
<pre>
get_Solid().add(newItem);
</pre>


<p>
Objects of the following type(s) are allowed in the list
{@link JAXBElement }{@code <}{@link CompositeSolidType }{@code >}
{@link JAXBElement }{@code <}{@link SolidType }{@code >}
