wind_directions_validator(instance, value)[source]#
Return type:

None

Parameters:

  • instance (Attribute) --

heterogeneous_config_validator(instance, value)[source]#

Using the validator method to check that the heterogeneous_inflow_config dictionary has the correct key-value pairs.

Return type:

None

Parameters:

  • instance (Attribute) --

  • value (dict | None) --

het_map_validator(instance, value)[source]#

Using this validator to make sure that the het_map has an interpolant defined for each findex.

Return type:

None

Parameters:

  • instance (Attribute) --

  • value (list | None) --

initialize_velocity_field(grid)[source]#
Return type:

None

Parameters:

grid (Grid) --

finalize(unsorted_indices)[source]#
calculate_speed_ups(het_map, x, y, z=None)[source]#
generate_heterogeneous_wind_map()[source]#

This function creates the heterogeneous interpolant used to calculate heterogeneous inflows. The interpolant is for computing wind speed based on an x and y location in the flow field. This is computed using SciPy's LinearNDInterpolator and uses a fill value equal to the freestream for interpolated values outside of the user-defined heterogeneous map bounds.

Args:

heterogeneous_inflow_config (dict): The heterogeneous inflow configuration dictionary. The configuration should have the following inputs specified.

  • speed_multipliers (list): A list of speed up factors that will multiply

    the specified freestream wind speed. This 2-dimensional array should have an array of multiplicative factors defined for each wind direction.

  • x (list): A list of x locations at which the speed up factors are defined.

  • y: A list of y locations at which the speed up factors are defined.

  • z (optional): A list of z locations at which the speed up factors are defined.
