1.2.2 Concentration in Time

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

Element concentration in time (syntax)

$\begin{figure}\centering \begin{tabbing} \texttt{'CONCEN'} \\ {[}\,\texttt{ELE... ...ts}\,\) \texttt{/} \\ [.5ex] \>\>\emph{concentration} \end{tabbing} \end{figure}$

Nodal concentration in time (syntax)

$\begin{figure}\centering \begin{tabbing} \texttt{'CONCEN'} \\ \texttt{NODES} \... ...ts}\,\) \texttt{/} \\ [.5ex] \>\>\emph{concentration} \end{tabbing} \end{figure}$

ELEMEN

is an optional subtable name for element concentrations.

NODES

is the subtable name for nodal concentrations.

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

t1 ...tn

are the times t at which the concentrations are specified.

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.

concentration

are the values of the concentrations C (and $\Delta$ C ) at times t .
