is an integer value greater than or equal to 0.įile: The name of the sub file in this dataset.

Part: The identification number of this part of the current dataset. Lists the unique assigned identifier of the source, reader, or filter that created this dataset. Set the compression method, such as “vtkZLibDataCompressor”. Most consumer-level laptops and desktops use little endian older clusters and supercomputers may use big endian.Ĭompressor: Optional. Depends on the endianness of the platform on which this file is written. Version: The version, currently the default is 0.1.īyte_order: For binary storage format, “BigEndian” or “LittleEndian” needs to be set. Type: The type is “Collection”, which means containing a set of data files. This is a necessary feature for transient analysis post-processing. Most vital is the defined time for each sub file, which can be used to display the result time in postprocessing. ParaView data (pvd) file is an xml file built on the top of the VTK system. The relation between the pvd, pvtu, and vtu data formats is shown in the figure below: ParaView Data File Format For complex transient analyses, users can easily export the results to ParaView for subsequent analysis and report generation. WelSim also supports exporting pvd result data in the latest version. As a result, this shows the pvd+pvtu+vtu method is one of the most versatile solutions for simulation engineering. This feature is impactful for large simulation projects. While the computer is reading and generating the files in parallel mode, the multi-core parallelism is applied to improve the file processing efficiency. Based on the vtu format, VTK provides the pvtu format when parallel computing. WelSim has provided exporting results in vtu format for several years.

Here the letter U means unstructured mesh. The vtu file, which and supports both ASCII and binary encoding, is the main file for storing the mesh generation and result data. Essentially, the pvd file is the entry file of multiple sub result files, some commonly used sub-files are pvtu and vtu files. When simulation result data is solved using the finite element or finite volume method, the most general and exceptionally efficient format is ParaView Data (pvd), which is why the latest version of WelSim can export result data in pvd format. ParaView supports a large number of input file formats, including the notable CGNS, UNV, NetCDF, VTK, TecPlot, as well as the molecular dynamics software: LAMMPS, and more. Paraview is prominently applied in the field of scientific computing, especially during the post-processing. Furthermore, Paraview supports various types of computers and clusters in terms of visualization and data processing. Users can apply its 3D interaction or batch processing features to quickly create visualizations for data analysis. ParaView is a powerful and open source 3D data visualization tool.
