Converts a CAESAR II input file to a neutral file or converts a neutral file to a Converts a CAESAR II input file.
The CAESAR II neutral file, an ASCII text file with the .cii extension, enables access to any particular data item from an _A input file, to enable a complete _A file to be built from a CAD application. The .cii file can be used to send data either to or from the _A file. The name of the file used or generated by this interface is the CAESAR II jobname.
The content and format described in this section is subject to change as a function
of the enhancements made to CAESAR II. Every effort is being made to keep "drastic" changes to a minimum.
Several third-party CAD applications, such as AVEVA®’s PDMS®’ and Jacobus’ PlantSpace™, also support this neutral file. If you prefer, instead of launching this interface from Tools > External Interface, the processor can be run in "batch mode" from either a batch file or the command line as shown below.
f:\ProgramDirectory\iecho f:\DataDirectory\NeutralFile.cii
where:
f:\ProgramDirectory and f:\DataDirectory must be changed as appropriate.
The .CII file, is divided into sections which organize the piping data in logical groupings. Section divisions are denoted in the neutral file by the ‘#$’ character sequence found in columns 1 and 2. The token following the #$ character sequence is a section identifier that is used by CAESAR II for data sequencing purposes, and to aid you in reading the neutral file. For each item listed on the following pages, the necessary FORTRAN format for the input/output is provided. The variables listed below are used in dimensioning arrays.
-
N1—Base memory allocation quantity used to set array sizes. For example, if N1=2,000, your neutral file can handle up to 2,000 elements.
-
N2—1/2 N1
-
N3—1/3 N1
-
N4—1/4 N1
-
N5—1/5 N1
-
N6—N1/13.33
