constraints SectionΒΆ

This section configures constraints for the model, including elevation clamping, nudging, and relaxation parameters.

Parameter

Description

use_internal_specifications

Flag to use internal specifications for constraints (TRUE, FALSE).

elevation_constraint_file

File containing elevation constraints (clamped or nudging).

constraint_method

Method for constraints (CLAMPED, NUDGING).

constraint_start

Start time for applying constraints (default: 0 h).

relaxation_time_scale

Time scale for nudging relaxation (default: 300 s).

relaxation_length_scale

Length scale for nudging relaxation (default: 1000 m).

relaxation_extent

Extent length for nudging relaxation (default: 1000 m).

max_data_gap

Maximum allowed data gap for constraints (default: 600 s).

apply_spatial_gradient

Flag to apply spatial gradient in constraints (TRUE, FALSE).

echoing_file_template

Template for echoing model values at constraint locations.

echoing_interval

Interval for echoing constraint values (default: 300 s).
