4.3. Create3D
A Portable Tool for creating files for 3D Visualization (r314)
Creating files from GASFLOW-MPI dump files (e.g. gfd00001.nc) for 3D visualizations using either Xdmf files for programs like ParaView or VisIt or .plt files for Tecplot.
For Xdmf output two files will be created, one XML file (.xmf) and one HDF5/netCDF4 (.nc) file. Both files are required for ParaView or VisIt.
For Tecplot one .plt file will be created.
GASFLOW-MPI has the option to produce files containing only the data required for visualization. These files are significantly smaller than the full dump files used for calculation restart.
Usage
create3D [-h] [--output OUTPUT] [--xdmf3] [--compression {0,1,2,3,4,5,6,7,8,9}] [--spatial] [--turbulence] [--time-format TIME_FORMAT] [--tecplot] [--buffer-size BUFFER_SIZE] [--particles {none,plain,density}] [--splitnumbers] [--startnumber STARTNUMBER] [--grid GRID GRID GRID] [--hex-mesh] [--gui] [--debug] [--version] [file [file ...]]
Examples
Open create3D with GUI
Converting one dump file, gfd00035.nc, to Xdmf files
Converting one dump file, gfd00035.nc, to .plt files with turbulence
Converting all the dump files in one folder to Xdmf files
Converting one dump file, gfd00001.nc, to Xdmf files with particle 'cloud' and 'density' array
--spatial must be included when particle data needs to be converted
Converting all the dump files, gfd*.nc, to Xdmf files with particle 'cloud' and 'density' array using the user-defined grid
--spatial must be included when particle data needs to be converted
--grid x__num y__num z_num user-defined grid to plot the particle density
Positional arguments
file
GASFLOW-MPI dump files (gfd*.nc). This is a required parameter unless the GUI is used. (default: None)
Optional arguments
-h, --help
show this help message and exit
--output OUTPUT
Name of the output files excluding the extension. If more than one input file is given, the output file names are generated by adding a 5 digit numbering starting at 1 to this name. If 3 input files are given, the default output names will be visout00001, visout00002, visout00003. (default: visout)
--xdmf3
Produce Xdmf version 3 compatible format. Warning: This most likely only works with the "Xdmf3ReaderT" of ParaView. It will currently not work with VisIt. VisIt only support Xdmf version 2. (default: False)
--compression {0,1,2,3,4,5,6,7,8,9}
zlib compression level for Xdmf output, 0 disables compression. Ignored for Tecplot. (default: 4)
--spatial
Add a spatial collection around the various meshes. Needed for ParaView and Ensight. Ignored for Tecplot. (default: False)
--turbulence
Write turbulence parameters if available. (default: False)
--time-format TIME_FORMAT
Format for the time in the Xdmf file. There is no need to change this unless there are problems. Ignored for Tecplot. (default: 14.4f)
--tecplot
Produce output in Tecplot binary format (.plt). (default: False)
--buffer-size BUFFER_SIZE
The size of the buffer for some output when manipulating Tecplot files. Ignored for Xdmf output. (default: 1048576)
--particles {none, plain, density}
If the argument value is 'plain' create a Polyvertex mesh for the particles. If 'density' is given, try to calculate a particle density. Only for XDMF output. (default: none)
'none': No particle output (the default).
'plain': Just the particle cloud.
'density': Output particle cloud and density array.
--splitnumbers
Take the same trailing digits as the input file name(s) and add these to the output file name(s). (default: False)
--startnumber STARTNUMBER
Use this number as the initial number for the generation of the output file names. Will be ignored, if the --splitnumbers option is used. (default: 1)
--grid GRID GRID GRID
Dimensions of the new grid generated for the particle density. Use this option to generate an independent (and finer) mesh for the particles instead of using the original mesh for the fluid. (default: [30, 30, 10])
--hex-mesh
Use an unstructured hexahedral mesh for the fluid cells, thereby avoiding problems with data in obstacle cells. (default: False)
--gui
Start the GUI. (default: False)
--debug
Enable debug output to the log file. (default: False)
--version
Show the some version numbers and exit. (default: False)
