Abstract

Reference handling in the GRASPS program for reflector antenna analysis N.C. Albertsen^, P.E. Frandsen', SB Serensen' & M. Lumholt' 'TICRA Engineering Consultants, Denmark s* Institute for Mathematical Modelling,The Technical University of Denmark Abstract GRASPS is an Object Oriented (OO) Fortran 90 program for analysing general reflector antennas and antenna farms. In a recent study for ESTEC the program has been extended with methods for Interface Definition handling, semantics checking and handling of complex mutual object references. Corresponding features have been implemented in the general GPAD pre-processor. The design and structure of the program is outlined from a software engineering point of view and the features of the pre-processor are summarised, including the interface to the analysis program and to the user. Some important classes are mentioned and the managing of interface definition and references is discussed. 1 Introduction GRASP8W is an integrated t
