logical parameters::batimetry_function_flag

Flag to choose in which way we upload the batimetry.

T => through a function

Definition at line 37 of file parameters.f90.

type(bc), dimension(n_vars) parameters::bcl

blL&flag defines the left boundary condition:

bcLflag = 0 => Dirichlet boundary condition;

gradient of the variable for Neumann boundary condition (bcLflag=1).

Definition at line 95 of file parameters.f90.

type(bc), dimension(n_vars) parameters::bcr

blR&flag defines the right boundary condition:

bcRflag = 0 => Dirichlet boundary condition;
bcRflag = 1 => Neumann boundary condition.

bcRvalue is the value of the right boundary condition:

value of the variable for Dirichlet boundary condition (bcRflag=0);
gradient of the variable for Neumann boundary condition (bcRflag=1).
