The fieldsExpression function has been generalised to work with a
general operator. Existing functions "add" and "subtract" have been made
to use this system, and two new operations, "multiply" and "divide",
have been added.
The functions can now handle multiple types in both input and output. A
multiply (outer product) operation on two vectors and a scalar will
result in a tensor. If the operation chain is not supported (e.g.,
division by a vector) then a warning will be generated.
In addition, a "uniform" function has been added, which will create a
uniform geometric field of a given type with specified dimensions and
calculated boundary conditions. This is mostly useful for testing
purposes and for conveniently creating simple input fields for the
operation functions described above. The function can be called by
postProcess as follows:
postProcess -func "uniform(fieldType=volScalarField, name=length, dimensions=[m], value=2)"

About OpenFOAM
OpenFOAM is a free, open source computational fluid dynamics (CFD) software package released by the OpenFOAM Foundation. It has a large user base across most areas of engineering and science, from both commercial and academic organisations. OpenFOAM has an extensive range of features to solve anything from complex fluid flows involving chemical reactions, turbulence and heat transfer, to solid dynamics and electromagnetics.
