Detailed Description

Unit testing for the linear FE solver.

The purpose of this file is to provide some unit/regression tests for various FE models, on a low level. It also covers parsing of Nastran bulk data files containing the FE model definition. For each model, the linear- elastic stiffness matrix is assembled, and solved for some external load (defined in the FE data file). Then the response at one node is compared against the reference values (u_x, u_y, u_z).

	)

Instantiate the test over a list of file names, node for which to extract displacements, and associated reference values to compare with.

main()

int main	(	int	argc,
		char **	argv
	)

Main program for the FE solver unit test executable.

operator<<()

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

Global stream operator to print out a Case instance.

solvePartDis()

int solvePartDis	(	int	,
		const int *	,
		double *
	)

From reducerInterface.C.

TEST_P()

TEST_P	(	Solve	,
		FEmodel
	)

Creates a parameterized test reading a FE data file, solving it, and comparing the nodal response with given reference values. GetParam() will return a Case instance, with the actual file name, node number and displacement values at that node to compare the response against.
