Detailed Description

Unit tests for the dynamics solver.

The purpose of this file is to provide basic unit-tests for some simple models, as an alternative to the regression tests in solverTests. We here focus more on basic functionality of the vpmSolver module, which is accessed via the solverInterface API, and uses google test for checking the behaviour and also for comparing response variables against reference values.

INSTANTIATE_TEST_CASE_P()

INSTANTIATE_TEST_CASE_P	(	TestSystemBeam	,
		Solve	,
		testing::Values(Case{ "cantilever-pipe", 17, { 0.344609, 0.0, 9.992951, 0.344609, 0.0, 9.992951, 0.344609, 0.0, 9.992951 }, false }, Case{ "cantilever-pipe", 17, { 0.345020, 0.0, 10.00000 }, true }, Case{ "cantilever-noshear", 17, { 0.343424, 0.0, 10.00000 }, true })
	)

Instantiates the unit tests Solve.SystemModel.

main()

int main	(	int	argc,
		char **	argv
	)

Main program for the dynamics solver unit test executable.

operator<<()

std::ostream& operator<<	(	std::ostream &	os,
		const Case &	c
	)

Global stream operator to print out a Case instance.

TEST()

TEST	(	Solve	,
		Prescribed
	)

Creates a solver unit test for linear static analysis.

This reads the solver input file, solves each time step and compares the control response variables against the reference values. Finally it closes down the solver to clean up memory.

TEST_P()

TEST_P	(	Solve	,
		SystemModel
	)

Creates a parameterized solver unit test.

This reads the solver input file, solves the initial equilibrium configuration and compares the control response variables against the reference values, then (unless it is a linear static analysis only) it invokes the time step loop comparing the response after each time step. Finally it closes down the solver to clean up memory.

GetParam() will return a Case instance, with the actual file name, baseID of the triad to compare the response at, and its reference values.
