PATFID is an interactive program which translates a model developed in the interactive graphics program PATRAN into an acceptable format for the fluid dynamics program FIDAP. The engineer wishing to analyze a problem in fliud flow or heat conduction first uses PATRAN top create a finite element model consisting of nodes, elements, and boundary conditions, following the instructions provided in this manual. The PATRAN neutral file containing this model is then supplied to PATFID, which prompts the user for all additional information needed for FIDAP. The specific questions that the user is asked depend upon the nature of the model developed in PATRAN and upon answers to previous questions. A print file, containing all messages to and from the user, and a session file, which can be used to supply user responses in a later run, are automatically generated by PATFID. The output file from PATFID is a complete and internally consistent input file for the FIDAP pre-processor FIPREP. PATFID is a FORTRAN-77 program implemented on VAX computers. It will translate any neutral file appropiate for FIDAP created by any version of PATRAN at least up to 2.0 into the FIPREP input file for Version 3.0 of FIDAP. Fluid problems which can be prepared for FIDAP using PATFID include two- and three-dimensional problems with pressure, heat flux (including radiative and convective flux), velocity, and temperature boundary conditions and velocity and temperature initial conditions. PATFID utilizes subroutines from the TRANSL subroutine library for PATRAN translators. 8 refs., 5 figs., 0 tabs.
