configuration via a configuration file

The run of libraries is controlled by a configuration file. By this file, a user is able to manage every single parameter of the libraries. The following file is an example of the configuration file for loading a mesh from an ANSYS CDB database and set the solver for heat transfer (see benchmarks directory for more examples).

INPUT {
  FORMAT           ANSYS_CDB;
  PATH    <path_to_database>;
}

OUTPUT {
  FORMAT ENSIGHT;
  PATH   results;
