Introduction

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

Many users use the software “right out of the box” even though there are many ways to improve input efficiency and comfort Screen organization

The CAESAR II Configuration (CFG) File

The Configuration File (i.e. CAESAR.CFG) hold 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.

Be aware of when the change occurs (“activation point”):

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- Material Data

CAESAR II has hundreds of materials

But maybe not yours

You can define these materials locally:

Or, you can add your material to the CAESAR II database

Edit, then Search

Your work will not alter the CAESAR II data (stored in CMAT.BIN)

Instead, your data (stored in UMAT1.UMB) will overlay any existing data

These files reside in SYSTEM:

Editing/Adding Stored Content- Displacement Sets

Modular piping offshore can have many imposed displacements at many connection points –requiring many displacement sets

This data entry can be automated

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.

The response spectrum data can be “linked” to the dynamic input.

Here is the processed data.

Building standard load case lists

Many firms have standardized their load sets

In more and more instances, these are very comprehensive

Seismic, wind, blast

FPSO

Fatigue

… and therefor, tedious and prone to error

You can copy existing load cases from one job to another

Recall seeing these *.INP files in the SYSTEM folder?

The INP files set the format for the input lists.

Here is the beginning of the default element report format (ELEMENT.INP & ELEMENT0.INP):

Here is another – ELEMENT1.INP:

CAU Express 2013 27


© Intergraph 2013


CAESAR II uses the “base” .INP file without a numeric suffix (e.g. ELEMENT.INP)

The files with the numeric suffix are available for use (e.g. ELEMENT1.INP)

You can build your own format files as well

Copy the selected file into the “base” name to apply
