Detailed Description

Set the reference pressure in the computational domain for ABL simulations.

This algorithm sets the reference pressure at an internal computational node that is used as a reference for the Continuity equation. Reference pressure is necessary in situations where all the boundaries are either periodic or symmetry, e.g., precursor simulations where the sides are periodic and the top boundary is usually set to symmetry.

The reference pressure can be activated by adding the section abl_fix_pressure to the solution_options for the relevant realm as shown below:

solution_options:
  name: ablSimOptions

  fix_pressure_at_node:
    node_lookup_type: spatial_location      # Use nearest node search
    value: 0.0                              # Reference pressure
    location: [10.0, 10.0, 10.0]            # Spatial location where pressure is referenced
    search_target_part: [Unspecified-2-HEX] # List of mesh parts to be searched
    search_method: stk_kdtree               # Search method to determine nearest node

Alternately, the user can specify an STK node identifier instead of performing a search for the nearest node.

solution_options:
  name: ablSimOptions

  fix_pressure_at_node:
    node_lookup_type: stk_node_id           # Use STK node identifier
    node_identifier: 33662                  # STK Node ID
    value: 0.0                              # Reference pressure
