Input types

OpenFOAM input dictionaries are designed to be human-readable ASCII text files, consisting of collections of keyword-value entries bounded by curly braces {}, e.g.

dictionary_name
{
    labelType       1;
    scalarType      1.0;
    vectorType      (0 0 0);
    wordType        word;
    stringType      "string";
    ...
}

The main basic entry types include:

Type Description Example
boolean state on, off, true, false
label integer 123
scalar float 123.456
word a single word value
string quoted text "this is a string value"
list a list of entries bounded by () braces (0 1 2 3 4 5)
vector a list of 3 values, nominally (x y z) components (0 0 0)
sphericalTensor a spherical tensor (0)
symmTensor a symmetric tensor defined by (xx xy xz yy yz zz) (0 0 0 0 0 0)
tensor a nine component tensor defined by (xx xy xz yx yy yz zx zy zz) (0 0 0 0 0 0 0 0 0)
