readNasScalar()

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

static

nextNasField()

std::string nextNasField ( const std::string &  str, std::string::size_type &  pos, const std::string::size_type  width, const bool  free_format = false  )

static

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

Returns the substr until the next comma (if found) or the given fixed width

Parameters

	str	The string to extract from
[in,out]	pos	The parse position within str
	width	The fixed-format width to use (if comma is not found)
	free_format	The input is known to be free-format

writeKeyword()

Foam::Ostream & writeKeyword ( Ostream &  os, const word &  keyword, const fieldFormat  format  )

static

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

Definition at line 196 of file NASCore.C.

faceDecomposition()

Foam::label faceDecomposition ( const UList< point > &  points, const UList< face > &  faces, labelList &  decompOffsets, DynamicList< face > &  decompFaces  )

static

Calculate face decomposition for non tri/quad faces.

Parameters

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

Returns

number of decomposed faces
