CEA Legacy Interface

The CEA legacy interface is designed for backward compatibility with older versions of the software (ie CEA2). The CEA2 interface uses the text-based file format for input and output described in RP-1311 Part 2 [1].

Usage

To use the legacy interface, call the compiled cea module from the command line with the following syntax: ` ./cea <input_file> ` where <input_file> is the path to the input file in the legacy format, without the .inp extension. The output will be written to a file with the same name as the input file with a .out extension. By default, the compiled cea module will be placed in the build directory after compiling the program.
