The developments of computational tools have been rising enormously in engineering applications. The robustness of interpretation of results from a computer tool mainly depends on the post processing. The complex analysis using finite element method needs visualization of results on various engineering parameters. This paper presents the work carried out for the development of a graphical user interface, named as XRAPS for a finite element package FINEART. The program is developed using the X Window system for creation of the interfaces. An object oriented technology is used for user interface objects/ widgets. A direct linking strategy is employed for interfacing of legacy Fortran modules to offer a single window system to users of XRAPS. XRAPS is menu driven, single window and leads to direct display in post processing. Keywords: XRAPS, Finite Element Analysis, structural responses, X Windows, Post-processor, GUI.
