Most of the CAESAR II executable modules have been converted from Microsoft 16 bit FORTRAN to WATCOM 32 bit FORTRAN. This has reduced the low DOS RAM requirements of the software from 577k to 475k.

The modules converted to 32 bit operation for Version 3.21 are summarized below:

  • Static Stress Computation Module (1)

  • Piping, Buried & Structural Steel Input Modules (3)

  • Piping Error Checker (1)

  • Load Case & Dynamic Input Module (1)

  • All CAD interfaces (8)

  • Neutral File interfaces (2)

The software now supports an ESL from a new vendor. This provides CAESAR II with full networking abilities. The software first checks for a local ESL (from either vendor), then for a network ESL.

Toward the support for network operations, the data files which are not job specific are now assumed to be located in a SYSTEM subdirectory underneath the CAESAR II installation directory. These data files include: the input listing formatting files (*.INP), the accounting data files, the printer formatting file, the file handler template file, and the various header files.

The common factor among all of these files is that they are specific to a company installation, not a particular data directory. Up until Version 3.21, these data files were manipulated by the software (or sometimes directly by you) in the installation directory. However, many network installations “write protect” their installation directories, making modifications to these files impossible. These files are placed in a SYSTEM subdirectory to which you should be given complete access.

CAESAR II Version 3.21 is capable of running on a local machine (with either vendor’s local ESL) or on a network (with the network ESL). The changes made to the software enable the same version to be run under these various configurations.

  • Added additional spring hanger manufacturer has been added, Carpenter & Paterson, UK.

  • The UBC (Uniform Building Code) earthquake spectra have been added.

  • The B31.5 piping code has been added.

  • The piping code addenda have been reviewed and any necessary changes made to the software. The addenda include revisions for: ASCE #7, B31.1, B31.8, ASME NC, and ASME ND.

  • The SIF scratch-pad from the Miscellaneous processor (Option C of the Main Menu) has been incorporated into the piping preprocessor. This processor includes all of the supported piping codes (not just B31.1 and B31.3 as before) and all of the fittings. Additionally, any changes made to the scratch-pad data can optionally be transferred directly to the main CAESAR II data spreadsheets.

  • Additional changes to the input piping preprocessor include the following:

    problem size is now dependent on the amount of free extended memory - the old limit of 400 elements is now upwards of 8,000 elements

    graphics menus automatically turned off for hard copies

    optional node number display for supports, anchors, hangers, and nozzles

    function key map shown on main spreadsheet

    auxiliary input spreadsheets support help

  • The accounting system has been completely rewritten. This provides a more streamlined interface. Additionally, accounting statistics are now recorded from the stress computation modules (previous versions only recorded the actual matrix decomposition times).

  • The API-617 and NEMA-SM23 reports have been overhauled so that the code compliance when using non-English units systems is consistent.

  • The new Flange Rigidity factor from ASME Section VIII has been added.

  • A new loader (C2.EXE) has replaced the original one (C2.COM). This new loader performs initial startup checks, with diagnostic reporting if necessary, and enables error processing from the Main Menu.

  • The configuration program has been modified to track changes. If you attempt to [Esc] out after making changes, you are warned that the changes will not be saved.

  • A graphics viewer has been added to the file manager. This enables rapid model plotting directly from the file manager of the Main Menu.

  • Additional directives are available to disable the generation of the Table of Contents page, and disable the display of the spreadsheet function key mapping.
