Did you know ?
It is generally good practice to ensure that the minimum natural frequency of any piping system is above 4Hz to reduce likelihood of vibrations.
Introducing Salad Print

Xtrados is pleased to introduce Salad, the scriptable post processor for CAESAR II®.  Now you can speed up time consuming tasks such as performing supplementary calcs, creating stress summaries and lists.

What Can it Do For Me ?

  • Have you got an off-axis nozzle and would like to know the local loads for all load cases ?
  • Would you like to quickly generate an Excel spreadsheet summary of your calculation ?
  • Are you doing an API 617 compressor nozzle load summation and wonder how all your other load cases compare ?
  • Perhaps you have an off-axis piping run and would like to see a restraint summary in local co-ordinates.
  • Would you like to harness the CAESAR II Material Database to carry out a wall thickness calculation ?

Salad comes with example scripts to carry out these tasks and more.  All scripts are fully customisable to your own needs and preferences.

What Else Could I Do With It ? Image

These are a few applications we can come up with, but don't feel limited to just these -

  • Carry out alternative code checks or interpretations
  • Make a list of springs on your project
  • Generate a list of structural supports using your project's criteria
  • API 610 check for all your load cases
  • MTD Guideline assessment for flow-induced vibration
  • Vessel nozzle check for project with defined allowable nozzle loads
  • Trunnion calculations

You can also use Salad for most calculations normally written in spreadsheet or math applications.  Which brings us around to the..

English-like Scripting Language

Don't struggle with Visual Basic macros or long nested 'If' statements, trying to make Excel do something its not best suited to.  Salad offers you an easy to learn, English-like programming language, making it ideal for calcs or assessments that follow a flow-chart approach - such as a Fitness for Service assessment for example.

(In case you're wondering, Salad employs the Revolution™ language, which has been in use and continually developed for over a decade.  Xtrados has added in custom features and functions for Salad that let you conveniently extract the data from your CAESAR II analysis.)

Having said all of the above, if you're like us you've probably grown pretty attached to your spreadsheets, which is why we've designed Salad to..

Work with Excel  Image

Let Salad cherry-pick the data from your stress analysis and pass it on to your existing or new spreadsheets for calculation.  Or take advantage of Salad's scripting capabilities for the heavy lifting and just use Excel for final presentation.

Maybe you want to program one of those big spreadsheets with loads of look-up tables.  You could well end up with a tangled web of formulae, cell ranges that musn't be edited and hidden columns.  Instead, why not store the data in Excel and use Salad to retrieve it and do all the processing.  This will make future changes and debugging easier.

How Does it Interact with CAESAR II ?

Salad works with XML data which you export from CAESAR II using the Data Export Wizard (See Tutorial 1). We're hopeful that Salad may earn its own slot on CAESAR II's 'External Interfaces' menu in time.  If you find Salad useful or potentially useful, please let COADE know that you would like to get more streamlined data export.
