The [ansys::CffProvider](classansys_1_1_cff_provider.xhtml "Class that provides functions to access data stored within a CFF database. The database may be stored...") class allows a CFF case file or a pair of CFF case and results files that were produced by an Ansys application that supports this format to be read and processed by your application.

This class has methods to open a specific file and read the available, mesh, topology, physics, and settings information from the CFF case file and/or solution and settings data from the CFF results file.

An object of this class can be created using a 'C++' factory function ([ansys::getDataProvider](namespaceansys.xhtml#a2f23564ea3eec12f9b204a64356e88c1 "A function that provides that obtains an instance of an ansys::CffFileProvider that can be used to re...")) and subsequently used directly.

NoteA set of wrapper functions are provided to allow access to the same functionality from a 'C' program.
