The following is a list of command-line arguments for navsetup:
|-h||Prints the list of parameters and a short description and prints the version number of NaSt3DGP.|
|-s SceneFile||Reads the scene description file SceneFile and generates a data-file|
|-b DataFile||The name of the data-file, the default name is default.bin|
|-l DataFile||load field variables(velocity, pressure etc.) from an existing datafile.
This is useful if you want to run a calculation with previsously computed values
to change some simulation parameters. You can create a binary file for the new calculation with the following command:
navsetup -s SceneFileNew -b DataFileNew -l DataFileThe data will be interpolated if the number of grid points changes.
|-L DataFiles||Same as -l, but reads several data files DataFiles.*.|
|-A TextFiles||Same as -L, but reads several text files (written by ) TextFiles.txt.*.|
|-o OutFile||This option sets the base of the filename to OutFile for the options which write files. If this option is not used, OutFile is set to 'default'.|
|-TC DataFile||Reads the data from the data-file and writes to Outfile.dat. The file format is ASCII Tecplot. The data written is located at the cell centers.|
|-T DataFile||same as but writes each field to a separate file named Outfile.field.dat, e.g. Outfile.u.dat .|
|-g DataFile||Reads the data from the data-file and writes each of it in Outfile.u, Outfile.v etc. These files can be read in Matlab with the script tools/matlab/ReadNast.m.|
|-a DataFile||Same as , but use ASCII-format(text files) which are named OutFile.txt.*.|
|-G DataFile||Reads the data from the data-file and writes each of it in Outfile.vtk.u, Outfile.vtk.v etc. The files are written in the VTK5.1 rectilinear grid format.|
|-GSDataFile||same as but uses the VTK Structured Points format and the files are named Outfile.vtksp.* .|
|-f||create a VTK file including the velocity-field or multiple scalars
This option has to be
used together with , e.g. use the command
navsetup -f -G DataFile -o Outfileto write the the velocity as a vectorfield and the pressure to a file named Outfile.vtk.mix or use
navsetup -f -G DataFile -o Outfileto write the pressure and the first two velocity components and .
