The CASE Analysis System is a library of individual computer programs which are used to analyze a cylinder kit component or a particular cylinder kit configuration. This User's Manual is designed to provide users with information on input data for the various CASE system programs. The CASE Analysis System is supported on the two operating systems: DOS and UNIX.
A description of the RING Analysis Program is given in Section 2 and a description of the PISTON Analysis Program is given in Section 3. A number of other programs are described in Sections 4 through 8. In addition to a brief description of the capabilities and limitations of the programs, each section lists the input data required to run that specific program. Some data is required while other data is optional.
The appendices contain a comprehensive discussion of input and output data. Appendix A contains a discussion on various systems of units. Appendix B describes input data files that must be created by the user. Appendix C defines units abbreviations used throughout the CASE Analysis System. Appendix D contains information on each allowable input data line for all CASE system programs. The formats for input data files are given in Appendix E.
The Case Analysis System is supported on the two Operating Systems: DOS and UNIX. For further description of the DOS version, refer to the release notes.
The Unix Version of the CASE Analysis System is delivered in the two compressed tar format files; the CASE Analysis System and ACE/gr plotting program. To install the System, proceed with the following:
1. Put the tar file into the directory under which you want to install the CASE Analysis System.
2. Decompress executable and auxiliary files by typing:
tar_xfv_filename
where the filename is the filename of the delivered compressed tar file (with an extension .tar).
3. Repeat steps 1 and 2 to install the ACE/gr plotting program.
4. To successfully run the CASE Analysis System, the following environment variables have to be specified.
CASE - CASE System Directory
CASE EDIT - a text editor you want to run to modify your data files. Default is: "VL."
CASE PRINT - a print command to get a hard copy of your data file. Default is: "lp."
CASE HELP - hypertext Browser (WWW Browser) such as Netscape, Mosaic, etc. Default is: "Netscape."
HOME_GR - the directory of ACE/gr executables.
An example of the data lines would be:
setenv_CASE_/usr/people/system/CASE
setenv_CASEEDIT_ textedit
setenv_CASEPRINT_ lpr setenv_CASEHELP_ /usr/people/smith/netscape/netscape2
setenv_HOME_GR /usr/people/xmgr
The environment variables can be specified either in the .cshrc file or a source file. For the .cshrc file, the above shown lines have to be added to the .cshrc file. For a source file, the same lines have to be put into the file which is actually a script file. To load the environment variable the following command has to be executed:
source_< source_filename >.
For more information about UNIX, .cshrc file or a script file, refer to your system manual or any UNIX handbook.
The CASE Analysis System contains an installation program (INSTALL.EXE) to handle the installation of the applicable files into a specified directory on the hard drive. In order to run the INSTALL program, the user must place the CASE Analysis System DISK 1 in drive A: and enter INSTALL at the DOS prompt from the A: drive. The user will then be prompted for applicable information for the installation process.
The default directory for installing the CASE Analysis programs is C:\CASE. However, the user may change this directory name if desired. In addition, the INSTALL program will also display additional modification information information pertaining to the AUTOEXEC.BAT file. The AUTOEXEC.BAT file must contain the following modifications:
PATH=%PATH%;path
SET CASE=path
where path is the directory where the CASE Analysis System of programs will be located. The environment variable CASE is used by the line/contour plot program (PLOTIT.EXE) and the finite element plot program (FEPLOT.EXE) to determine where their support files reside.
The CASE System Graphical User Interface (GUI) is an auxiliary program to provide easier data file editing, computational program executing, graphical data plotting, obtaining hard copies and animating.
The GUI represents a pop up window, a tool bar, pull down menues & scroll text areas for data file selection, data file editing, program execution and representation of graphical ouput and animation. The tool bar includes the following items:
File - data file selection, saving, printing, and program quitting.
Edit - data file editing.
Run - Running the computational programs with the selected data file as input. The computational programs are RING, PISTON, FEGEN, PHEAT, and PDIST. The description of these programs are given in the succeding sections.
Plot - Plotting graphical output from the computational programs using the ACE/gr plotting program. For the plotting options, refer to the description of teh computational programs output.
Animate - Animation of the computational program output. For more information, refer to teh computational program output and ANIMATE
Help - Getting Help
The scroll text area shows standard device output of the computational programs as well as system warnings and error messages.
N.B. The computational programs can be executed in a batch mode or from a command line, but GUI provides a much easier and more reliable way of program execution.
