LinDynamicSim

class sharpy.solvers.lindynamicsim.LinDynamicSim

Time-domain solution of Linear Time Invariant Systems

Uses the derived linear time invariant systems and solves it in time domain.

Requires a case_name.lininput.h5 file in the case root folder that contains:

• x0 (optional): Initial state vector

• input_vec: Input vector (n_tsteps, n_inputs).

Note

This solver is seldom used in SHARPy (its focus is on nonlinear time domain aeroelasticity) hence you may find this solver lacking in features. If you use it, you may need to make modifications. We would greatly appreciate that you contribute these modifications by means of a pull request!

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

Name	Type	Description	Default
write_dat	list(str)	List of vectors to write: x, y, u and/or t	[]
reference_velocity	float	Velocity to scale the structural equations when using a non-dimensional system	1.0
n_tsteps	int	Number of time steps to run	10
physical_time	float	Time to run	2.0
dt	float	Time increment for the solution of systems without a specified dt	0.001
postprocessors	list(str)		[]
postprocessors_settings	dict		{}
