From 4e7ae2bd201b94aecbe0d09cd37f168f3ec0c705 Mon Sep 17 00:00:00 2001 From: Gustavo Marques Date: Fri, 25 Mar 2016 09:10:58 -0400 Subject: [PATCH] New coordinate, rho, for the seamount test. Addded a rho coordiate test, which was missing. We made it working by adding MASS_WEIGHT_IN_PRESSURE_GRADIENT = True and making the min. thickness small (MIN_THICKNESS = 1.E-9). --- ocean_only/seamount/rho/MOM_input | 1 + ocean_only/seamount/rho/MOM_override | 9 + ocean_only/seamount/rho/MOM_parameter_doc.all | 1478 +++++++++++++++++ .../seamount/rho/MOM_parameter_doc.layout | 66 + .../seamount/rho/MOM_parameter_doc.short | 494 ++++++ ocean_only/seamount/rho/diag_table | 1 + ocean_only/seamount/rho/input.nml | 1 + 7 files changed, 2050 insertions(+) create mode 120000 ocean_only/seamount/rho/MOM_input create mode 100644 ocean_only/seamount/rho/MOM_override create mode 100644 ocean_only/seamount/rho/MOM_parameter_doc.all create mode 100644 ocean_only/seamount/rho/MOM_parameter_doc.layout create mode 100644 ocean_only/seamount/rho/MOM_parameter_doc.short create mode 120000 ocean_only/seamount/rho/diag_table create mode 120000 ocean_only/seamount/rho/input.nml diff --git a/ocean_only/seamount/rho/MOM_input b/ocean_only/seamount/rho/MOM_input new file mode 120000 index 0000000000..e0bd5dc71a --- /dev/null +++ b/ocean_only/seamount/rho/MOM_input @@ -0,0 +1 @@ +../common/MOM_input \ No newline at end of file diff --git a/ocean_only/seamount/rho/MOM_override b/ocean_only/seamount/rho/MOM_override new file mode 100644 index 0000000000..771ba35241 --- /dev/null +++ b/ocean_only/seamount/rho/MOM_override @@ -0,0 +1,9 @@ +!
