1.2.4 Pressure in Time

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

Element pressure in time (syntax)

$\begin{figure}\centering \begin{tabbing} \texttt{'PRESSU'} \\ {[}\,\texttt{ELE... ...g\ldots}\,\) \texttt{/} \\ [.5ex] \>\>\emph{pressure} \end{tabbing} \end{figure}$

Nodal pressure in time (syntax)

$\begin{figure}\centering \begin{tabbing} \texttt{'PRESSU'} \\ \texttt{NODES} \... ...g\ldots}\,\) \texttt{/} \\ [.5ex] \>\>\emph{pressure} \end{tabbing} \end{figure}$

ELEMEN

is an optional subtable name for element pressures.

NODES

is the subtable name for nodal pressures.

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

t1 ...tn

are the times t at which the pressures 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.

pressure

are the values of the pressure P (and $\Delta$ P ) at times t .
