#1760 closed Bug (fixed)

Creating child bathymetry with nesting tools from an existing child bathymetry does not work

Reported by: jchanut Owned by: jchanut
Priority: low Milestone:
Component: AGRIF Version: release-3.6
Severity: minor Keywords:
Cc: jchanut

Description

Context

Since global bathymetries at various resolutions already exist on ORCA grid, it is convenient to use them for nesting purpose. In other words one would like to use part of them as is, i.e. without any further interpolation on the child domain of interest. We expect that the nesting tool only performs the connection with the parent bathymetry at open boundaries.
The agrif_create_bathy tool handles this if the provided external bathymetry ("elevation_database") for the child domain:

  • has exactly the same size has the requested child domain
  • has exactly the same nav_lon/nav_lat arrays as the child coordinates

Analysis

This fonctionality does not work because the logical "Pacifique" is not initialized (to .FALSE.) in agrif_create_bathy.f90 which leads to the modification of longitude arrays, which precludes from exact longitude matching.

Fix

Set "Pacifique" to "false" in function Read_coordinates (agrif_readwrite.f90) if it is the case.

Simply initialize "Pacifique" to false in agrif_create_bathy.f90
