Dear PV Elite® User,

Intergraph CADWorx & Analysis Solutions would like to thank you for your continued feedback and support and let you know that the 2011 version of PV Elite has been released.


PV Elite 2011 Main Features:

Modeling of ASME VIII-1 Jacketed Vessels

What this feature does - Delivers an integrated approach leveraging the 3D model and calculations in the modeling of jacketed vessels (ASME App. 9) and vapor/distribution belts.

How this feature used -  Jackets or vapor belts can be added as details on cylindrical elements. Jackets can also span across element boundaries.

How this feature benefits you - Previously you would have to model the inner core vessel and the jacket sections as separate PV Elite models and then manually transfer the parameters between them. The same holds true for nozzles on the outer jacket and also the inner shell.
The old approach meant that results would reside in two or more places, meaning that reports would have to be manually combined. Moreover, you would have to apply correction factors to get correct combined wind and seismic loads. Another option would be to model the jacket/vapor belt in CodeCalc™, but then these items will excluded from any wind/seismic/support, and other calculations.

Why this is better than the old way of doing things
For starters it’s easier and quicker. With all the data in one model, there is less chance of errors from multiple inputs plus PV Elite automatically accounts for important interactions between the core vessel and jacket(s). The real-time 3D model, with intuitive sectioning capabilities, allows the on-screen display of the inner vessel plus jacket(s), which is a great in visualizing tool.

Modeling Tubesheet as Simply Supported

What this feature does - This feature provides an alternative method for modeling the welded joint between the tubesheet and shell or the tubesheet and channel cylinders, which can have the effect of reducing stress thereby producing a more economical design.

How this feature used - It is one of the optimization options available in the tubesheet tab of Heat Exchanger dialog.

How this feature benefits you - The tubesheet to shell or tubesheet channel junction is place of high stress. This alternative, permitted by the ASME code, gives you the option to produce a more economical, but also safe, design.

Why this is better than the old way of doing things - This new capability’s potentially more economical design option was not previously available in PV Elite. This meant that, in some cases, exchanger designers were limited to more conservative analysis therefore leading to more costly designs.

ASME Code Updates.

What this feature does
This feature includes all the rule updates in the ASME code addenda and material updates. The Imperial tables were completely re-created and the Metric ASME material tables were added.

How this feature used – This feature is included in the program automatically.

How this feature benefits you – You will be assured that your calculations are current and up to code.

Why is this needed – For code compliance, you must use the latest edition and addenda of the ASME.
