A majority of time allocated to pipe stress analysis is used in
building models

The CAESAR II Configuration (CFG) File
The Configuration File (i.e. CAESAR.CFG) holds many general
CAESAR II settings
A program installation dialog will establish the CFG file and
store it in SYSTEM
If no CFG in the local folder, CAESAR II will use the SYSTEM
CFG
Any changes to CFG in the local folder are stored locally
Use separate folders to separate differing CAESAR II
settings

The CAESAR II Configuration (CFG) File
Many program settings/switches are controlled in the
configuration file.

Adjusting plot update CAESAR II will update the plot after each
new
element is entered to include the entire model using the default
view (southeast)
If you wish to stay focused on a particular section, turn off
Refresh (This is automatically off on a return to an existing
model.)
Very large models may take time to update. You may wish to turn
off plot update altogether.

Editing/Adding Stored Content- Dynamic Data
Applied dynamic loads in the form of response spectra and time
histories can carry large amounts of data
Response spectra apply to all piping on a single floor of a
structure or to and entire plant area building once and using often
is an efficient approach
Transient hydraulic analysis tools can develop massive amounts
of load vs. time data for direct use as CAESAR II input.
Intergraph 2013
Editing/Adding Stored Content- Dynamic Data
CAESAR II provides methods to store these dynamic data sets
This dynamic data, whether provided by the structures group,
process engineers or produced by CAESAR II, can be stored on the
hard drive and attached to any set of dynamic input.
