\page us_vosy Examples of volume exchange coefficient computation for SYRTHES coupling (usvosy.f90)
The \ref usvosy subroutine is used to compute a volume exchange
coefficient for SYRTHES coupling.
\section usvosy_h_usvosy Examples
The following code blocks show two examples of computation of
a volume exchange coefficient.
\subsection usvosy_h_usvosy_arg Arguments of usvosy
\snippet usvosy.f90 arg
\subsection usvosy_h_usvosy_loc_var_dec Variable declaration
\snippet usvosy.f90 loc_var_dec
\subsection usvosy_h_usvosy_init Initialization
The values of the different fields that will be needed for the computation of the
volume exchange coefficient are retrieved.
\snippet usvosy.f90 init
\subsection usvosy_h_usvosy_1 Example 1
The first example corresponds to a constant volume exchange coefficient.
\snippet usvosy.f90 example_1
\subsection usvosy_h_usvosy_2 Example 2
The second example corresponds to a variable volume exchange coefficient
defined as follows :
\f[ h_{vol} = h_{surf} S \f]
with S is the surface area where exchanges take place by unit of volume and
\f[ h_{surf} = \frac{Nu \lambda}{L} \f]
