I'm having trouble reading and understanding this mathematical notation about conformal meshes:
$$\bar{\Omega} = \cup_{K\in T_{h}}K.$$
$\Omega$ is a domain, and $K$ is an element of $T_h$. $T_h$ is a conformal mesh of domain $\Omega$.
One, is this reading correct: $\Omega$ is the finite sequence elements, $K$, in $T_h$ in the collection $K$.
Two, what does this mean?
