NonLinearStatic¶

class sharpy.solvers.nonlinearstatic.NonLinearStatic[source]¶

Structural solver used for the static simulation of free-flying structures.

This solver provides an interface to the structural library (xbeam) and updates the structural parameters for every k-th step of the FSI iteration.

This solver can be called as part of a standalone structural simulation or as the structural solver of a coupled static aeroelastic simulation.

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 output to screen	`True`
`max_iterations`	`int`	Sets maximum number of iterations	`100`
`num_load_steps`	`int`		`1`
`delta_curved`	`float`		`0.01`
`min_delta`	`float`	Structural solver tolerance	`1e-05`
`newmark_damp`	`float`	Sets the Newmark damping coefficient	`0.0001`
`gravity_on`	`bool`	Flag to include gravitational forces	`False`
`gravity`	`float`	Gravitational acceleration	`9.81`
`relaxation_factor`	`float`		`0.3`
`dt`	`float`	Time step increment	`0.01`
`num_steps`	`int`		`500`
`initial_position`	`list(float)`		`<sphinx.ext.autodoc.importer._MockObject object at 0x7f8a2858e080>`
