NASCore ( )

default

Default construct.

Member Function Documentation

◆ readNasScalar()

Foam::scalar readNasScalar ( const std::string & str )

static

Extract numbers from things like "-2.358-8" (same as "-2.358e-8")

Definition at line 68 of file NASCore.C.

◆ nextNasField()

std::string nextNasField	(	const std::string &	str,
		std::string::size_type &	pos,
		std::string::size_type	len
	)

static

A string::substr() to handle fixed-format and free-format NASTRAN.

Returns the substr to the next comma (if found) or the given length

Parameters

str	The string to extract from
pos	On input, the position of the first character of the substring. On output, advances to the next position to use.
len	The fixed-format length to use if a comma is not found.

◆ setPrecision()

void setPrecision	(	Ostream &	os,
		const fieldFormat	format
	)

static

Set output stream precision and format flags.

		const fieldFormat	format
	)

static

Write initial keyword (eg, 'GRID' or 'GRID*') followed by the requisite number of spaces for the field-width.

	)

static

Write a GRID point.

Parameters

pointId 0-based Point Id

	)

static

Calculate face decomposition for non tri/quad faces.

Parameters

faces	the surface faces
decompOffsets	begin/end offsets (size+1) into decompFaces
decompFaces	List of non-tri/quad decomposed into triangles
