FoamRanges

• This libary provides a reference implementation of expression templates for OpenFOAM field arithmetic.

• The purpose here is to demonstrate the performance and implementation of the operations.

Compilation

• You will need a C++17 supporting compiler
• Source the latest OpenFOAM development version and run ./Allwmake

Running tests and benchmarks

• Go to a case folder which has fields p and U in 0 folder and type Test-Ranges --benchmark-no-analysis
• You will see various field operations carried out with the standard OpenFOAM style (old) and with the proposed ranges approach (new)
• If you only wish to run the tests without benchmarks you can type Test-Ranges Test*

Additional notes

• The unittest/mock_fields.H contains "mock" fields which are used to test the ranges implementation without reading mesh
• unittest/newGeometricField.H and unittest/newField.H are new field types which allow for direct construction from ranges
