Utilities

inflowStats

This utility allows to compute mean velocity and the diagonal components of the Reynolds stress tensor of a database of inflow fields. The database should be stored as an HDF5 file, see The HDF5 file format in Supported output formats.

The utility accepts two command line arguments.

  • --database, -d — the HDF5 file containing the inflow fields.
  • --writepath, -w — the location where to write the files containing the computed results.

It is possible to run it in parallel using MPI.

The utility will create the following files in the location specified by writePath

  • uMeanX, uMeanY, uMeanZ — contain the corresponding component of the mean velocity field.
  • uPrime2MeanXX, uPrime2MeanYY, uPrime2MeanZZ — contain the corresponding diagonal component of the Reynolds stress tensor.
  • y — the locations of the datapoints.

precursorStats

This utility allows to compute mean velocity and the diagonal components of the Reynolds stress tensor of a precursor database. The database should be stored as an HDF5 file, see The HDF5 format in Supported input formats.

The utility accepts two command line arguments.

  • --database, -d — the HDF5 file containing the inflow fields.
  • --writepath, -w — the location where to write the files containing the computed results.

It is possible to run it in parallel using MPI.

The utility will create the following files in the location specified by writePath

  • uMeanX, uMeanY, uMeanZ — contain the corresponding component of the mean velocity field.
  • uPrime2MeanXX, uPrime2MeanYY, uPrime2MeanZZ — contain the corresponding diagonal component of the Reynolds stress tensor.
  • y — the locations of the datapoints.

convertFoamFileToHDF5

This utility converts a precursor database stored in the foamFile format (see The foamFile format) to a database stored as a single HDF5 file, see The HDF5 file format.

The utility accepts the following command line arguments.

  • --precursor — The location of the precusor OpenFOAM case. This path will be used in order to locate the folder with the sampled velocity values.
  • --surface — The name of the surface that was used for sampling the values. The name is chosen in the cotrolDict of the case.
  • --filename — the name of the HDF5 file that will be produced.
  • --umean — The file containing the mean velocity profile. The file is assumed to have two or three columns, one with wall-normal coordinate, the second one with the values of mean streamwise velocity, and optionally a third one with the mean wall-normal velocity. If only two columns are present the mean wall-normal velocity is assumed to be zero.

It is possible to run the utility in parallel using MPI.
