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")

◆ 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
strThe string to extract from
posOn input, the position of the first character of the substring. On output, advances to the next position to use.
lenThe 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.

◆ 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

const fieldFormat  format 
)
static

Write a GRID point.

Parameters
pointId0-based Point Id

◆ 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
pointsthe surface points
facesthe surface faces
decompOffsetsbegin/end offsets (size+1) into decompFaces
decompFacesList of non-tri/quad decomposed into triangles
Returns
number of decomposed faces
