Load data from a *.txt file (specially created for the TVF NMCRC) or a regular FLUKA *.inp file.
To begin you must choose the type of input card - fixed or free format. Fixed format requires all fields (text, keywords, commands) to be aligned in columns of a set width. Free format allows input to be written anywhere on the line, with successive keywords separated by "separator" characters { , ; / \ : } - a manner similar to the list-oriented format of Fortran.
Finish by selecting the *.txt file or *.inp file from its directory and clicking "Open".
