IntegrateVertically Solver

General Informations

• Solver Fortran File: IntegrateVertically.f90
• Solver Name: IntegrateVertically
• Required Output Variable(s): given by the variable name
• Required Input Variable(s): Name of the variable to be integrated in Integrated Variable Name, Depth or Height
• Optional Output Variable(s): None
• Optional Input Variable(s): None

General Description

This solver compute the depth integrated value of a variable (sum_zb^zs D dz) or the mean value (1/H sum_zb^zs D dz). The resulting integrated value or mean can be computed on the upper surface or on the lower one. If the mean value is computed (Compute Mean = Logical True), the depth (if On Surface = Logical False) or the height (if On Surface = Logical True) has to be calculated. If the integrated variable is calculated on the upper surface (On Surface = Logical True), a Dirichlet BC has to be given at the bottom surface, and vice versa.
