flow_rate(number, format: Liters/Second, required): Volumetric design flow rate. Value specified will be either the system or per-borehole flow rate depending on the 'flow_type' set. Minimum: 0.
flow_type(string, required): Indicates whether the design volumetric flow rate set on on a per-borehole or system basis. Must be one of: ["BOREHOLE", "SYSTEM"].
max_eft(number, format: Centigrade, required): Maximum heat pump entering fluid temperature.
max_boreholes(number): Maximum number of boreholes in search. Optional. Applies to rectangular and near-square design algorithms. If unspecified, the search space will be bounded by the size of the GHE boundary.
continue_if_design_unmet(boolean): Causes to return the best available borehole field configuration rather than fail if design conditions are unmet. Optional. Default False.
