AerogridLoader

class sharpy.solvers.aerogridloader.AerogridLoader

AerogridLoader class, inherited from GridLoader

Generates aerodynamic grid based on the input data

The initial wake shape is now defined in SHARPy (instead of UVLM) through a wake shape generator wake_shape_generator and the required inputs wake_shape_generator_input. The supported wake generators are sharpy.generators.straightwake.StraighWake and sharpy.generators.helicoidalwake.HelicoidalWake.

The control_surface_deflection setting allows the user to use a time specific control surface deflection, should the problem include them. This setting takes a list of strings, each for the required control surface generator.

The control_surface_deflection_generator_settings setting is a list of dictionaries, one for each control surface. The dictionaries specify the settings for the generator DynamicControlSurface. If the relevant control surface is simply static, an empty string should be parsed. See the documentation for DynamicControlSurface generators for accepted key-value pairs as settings.

The initial_align setting aligns the wing panel discretization with the freestream for the undeformed structure, and applies this Z rotation at every timestep (panels become misaligned when the wing deforms). The aligned_grid setting aligns the wing panel discretization with the flow at every time step and takes precedence.
