What is action of function "gfs_domain_homogeneous_bc"?
In comments, it is stated that it applies the homogeneous version of the
boundary conditions of original variable to requested variable. What this
mean? does this mean that it applies homogeneous Dirichelet bc when defined
bc for original variable is Dirichlet (either non-homogeneous or
homogeneous) and applies homogeneous Neumann bc in the other cases?
If this understanding be correct, application of this function seems to be
questionable whan we have non-homogeneous Neumann bc, because when we have
Dirichlet bc variation of variable at boundary is zero (during
iterations) but it is not correct in the case of (non-homogeneous) Neumann
bc, e.g. assume we apply pressure gradient at input.
Stephane, could you please give me your comment?
