StaticUvlm¶

class sharpy.solvers.staticuvlm.StaticUvlm[source]¶

StaticUvlm solver class, inherited from BaseSolver

Aerodynamic solver that runs a UVLM routine to solve the steady or unsteady aerodynamic problem. The aerodynamic problem is posed in the form of an Aerogrid object.

Parameters:	data (PreSharpy) – object with problem data custom_settings (dict) – custom settings that override the settings in the solver `.txt` file. None by default

settings¶

Name-value pair of settings employed by solver. See Notes for valid combinations

Type:	dict

settings_types¶

Acceptable data types for entries in settings

Type:	dict

settings_default¶

Default values for the available settings

Type:	dict

data¶

object containing the information of the problem

Type:	PreSharpy

velocity_generator¶

object containing the flow conditions information

Type:	object

The settings that this solver accepts are given by a dictionary, with the following key-value pairs:

Name	Type	Description	Default
`print_info`	`bool`	Print info to screen	`True`
`horseshoe`	`bool`	Horseshoe wake modelling for steady simulations.	`False`
`num_cores`	`int`	Number of cores to use in the VLM lib	`0`
`n_rollup`	`int`	Number of rollup iterations for free wake. Use at least `n_rollup > 1.1*m_star`	`1`
`rollup_dt`	`float`	Controls when the AIC matrix is refreshed during the wake rollup	`0.1`
`rollup_aic_refresh`	`int`		`1`
`rollup_tolerance`	`float`	Convergence criterium for rollup wake	`0.0001`
`iterative_solver`	`bool`	Not in use	`False`
`iterative_tol`	`float`	Not in use	`0.0001`
`iterative_precond`	`bool`	Not in use	`False`
`velocity_field_generator`	`str`	Name of the velocity field generator to be used in the simulation	`SteadyVelocityField`
`velocity_field_input`	`dict`	Dictionary of settings for the velocity field generator	`{}`
`rho`	`float`	Air density	`1.225`
`cfl1`	`bool`	If it is `True`, it assumes that the discretisation complies with CFL=1	`True`
`vortex_radius`	`float`	Distance between points below which induction is not computed	`<sphinx.ext.autodoc.importer._MockObject object at 0x7f8a282cb080>`

next_step()[source]¶: Updates de aerogrid based on the info of the step, and increases the self.ts counter
