class
DataSourceVTF: public DataSourceInterface Data source interface for VTF model files.
The data source contains a collection of all states for one analysis. Each state groups together geometries and results for one time step, load case, frequency etc.
Each unstructured grid model owns one data source.
The DataSourceVTF is a subclass of DataSource. See DataSource on general functionality such as how to get states and metadata directory.
The VTF file format is Ceetron’s own format tailored specifically to carry structural mechanics and fluid dynamics data in a very compact form. For a thorough description of the VTF file format, see the reference guide: https://ceetron.com/wp-content/uploads/2018/04/vtf_glview7_reference_guide.pdf
Use open() to open a VTF file.
