compareResponse()

int compareResponse	(	const char *	fn1,
		const char *	fn2,
		double	eps,
		int	skip
	)

Utility function to compare two ASCII files with numerical data.

Parameters

[in]	fn1	Path to the first file
[in]	fn2	Path to the second file (with reference data)
[in]	eps	Comparison tolerance
[in]	skip	Number of initial lines to skip coomparison for

Here is the caller graph for this function:

extFunc()

static double extFunc ( int  id, double  x  )

static

Hard-coded external function evaluations to test against.

main()

int main	(	int	argc,
		char **	argv
	)

Test program for external functions in the dynamics solver.

Here is the call graph for this function:

printOut()

static void printOut ( std::ostream &  os, bool  formatted, double  time, const double *  outputs, size_t  nOut  )

static

Helper to print out response data to the given stream for a time step.

readFsiFile()

bool readFsiFile	(	const char *	cwd,
		const char *	fname,
		std::string &	chfsi
	)

Utility function to read a solver input file into a string variable.

Parameters

[in]	cwd	Current working directory
[in]	fname	Path to the solver input file on disk
[out]	chfsi	Text string containing the compressed file content

All blank lines and comment lines are ignored, and all white spaces are replaced by a single space character, to make the string more compact. A dollar-sign ($) is appended at the end of each line instead of the newline character, since the latter is not so well handled by the Fortran routines that read the solver input.
