In addition to new features described on other pages linked to from the version 2.0.0 release announcement, there are some other new developments in OpenFOAM. Other new solvers adjointShapeOptimizationFoam – steady-state solver for incompressible, turbulent flow of non-Newtonian fluids with optimisation of duct shape by applying ”blockage” in regions causing […]

Cyclic Boundary Condition The cyclic boundary condition, also know as a periodic boundary condition, treats 2 boundary regions as if they are physically connected. They are used for repeated geometries , e.g. heat exchanger tube bundles. In versions of OpenFOAM before v2.0.0, a cyclic patch contained the faces for both […]

Run-time Code Compilation OpenFOAM now includes the capability to compile, load and execute C++ code at run-time. It includes a new general directive called #codeStream that can be used in any input files for run-time compilation. For example, the following code in the controlDict file looks up dictionary entries and […]

Function Objects OpenFOAM can carry out post-processing (and run-time control) automatically while the simulation is running using function objects. In v2.0.0, the range of available functionality has been extended to include the following: abortCalculation – Watches for presence of the named file in the case directory and aborts the calculation […]
