REPORTING/ DOCUMENTATION OF CFD SIMULATION INPUTS AND RESULTS In order to open up CFD simulations to independent scrutiny within industrial organisations it is essential to have a comprehensive and uniform system of reporting. This is also useful as a basis for archiving simulations for future use with the ultimate aim of preserving past learning experiences and spreading best practice throughout groups of users within an organisation. First we suggest a list of items necessary for documentation of user input. INPUT DOCUMENTATION • General description of the problem and purpose of CFD simulation • Code chosen for solution of problem • Computing platform used for run • Schematic diagram of the region of interest with all key dimensions, flow inlets and outlets • Boundary conditions – include comments on/justifications of assumptions made and known areas of approximation or lack of information • Initial conditions for transient flow simulations or field initialisations for steady flow studies • Fluid properties – include comments/justifications of assumptions and data sources • Modelling option selections: (i) laminar/turbulent + turbulence model + near-wall treatment, (ii) combustion model, (iii) other physical models − with comments/justifications on selections • Grid design: temporal mesh, space mesh including one or more diagrams of the grid that are sufficiently clear to illustrate the approach to mesh design – also give written comments on compromises and details of grid-independence study • Solution algorithm choices – particularly non-default choices; note that default settings may change as a CFD code evolves, so a comprehensive summary of all the main selections (first/second-order schemes, multigrid options, segregated/coupled solver etc.) is preferable for…
