1.2.3 Maturity in Time

You may specify time dependent maturity in elements or in nodes.

Element maturity in time (syntax)

$\begin{figure}\centering \begin{tabbing} \texttt{'MATURI'} \\ {[} \=\underline... ...g\ldots}\,\) \texttt{/} \\ [.5ex] \>\>\emph{maturity} \end{tabbing} \end{figure}$

Nodal maturity in time (syntax)

$\begin{figure}\centering \begin{tabbing} \texttt{'MATURI'} \\ {[} \=\underline... ...g\ldots}\,\) \texttt{/} \\ [.5ex] \>\>\emph{maturity} \end{tabbing} \end{figure}$

matvar

is a subtable name which specifies the type of the maturity variable M : DGRREA for degrees of reaction, EQUAGE for equivalent age.

ELEMEN

is an optional subtable name for element maturity.

NODES

is the subtable name for nodal maturity.

If you don't specify a subtable, DIANA assumes element maturity. [ELEMEN]

If you don't specify the type of the maturity variable then DIANA assumes specification of the maturity via degrees of reaction. [DGRREA]

elm

is a single element number or elms is a series of elements specified with numbers or groups or both.

node

is a single node number or nodes is a series of nodes specified with numbers or groups or both.

maturity

are the values of the maturity variable M (and $\Delta$ M ) at times t . Depending on the subtable heading these maturity values are either the degrees of reaction r or the equivalent ages t_eq . For more details on the definitions of the maturity variable see also the section on hydration heat in potential flow analysis [§12.5].
