Input & Operation Features: 

Building even complex vessel models in PVElite is quick and easy. As each major element is added, the graphical display is updated to show the new element in relation to the others. This image confirms the content of the model. Clicking on the element in the plot brings up the tabular data for that element. As details (such as nozzles, insulation or trays) are added they too are illustrated, and clicking on them will bring up their data for review. Click on the image below to see the input in PVElite. 

PV-Elite designs to ASME Section VIII, Division 1, Division 2 and PD-5500.

Other geometries can also be confirmed graphically, namely basering layout and nozzle-shell junction. PVElite has an interactive 3D viewer that lets you review your model in great graphical detail.

PVElite has following basic elements: 

• Cylindrical Shells
• Elliptical, Spherical, Torispherical, Conical and Flat heads
• Conical Sections (including knuckles)
• Body Flanges
• Skirts with Basering details

following details can be attached on the basic elements:

• Stiffening Rings
• Nozzles
• Dead weight and applied loads
• Platform (both circular and rectangular) and Ladder
• Trays and Packing
• Saddles, Legs and Lugs
• Fluid
• Insulation and Lining

With a simply click on an icon, the component is added to the vessel. This provides a logical and intuitive modeling of the vessel. 

Other features include toolbars that can be positioned any way on the screen for optimum usability and a status bar that constantly displays an element's required thickness (due to pressure), vertical height, maximum allowable working pressure in operating condition (MAWP) and maximum allowable working pressure in new and cold condition (MAPnc). This insures that you are always aware of how changes to a design are affecting the vessel. You can also instruct the  program to automatically set the thickness of each element to the minimum required thickness, while inputting the vessel.

PVElite includes complete material property databases, for ASME Sec. VIII, Div. 1 and Div. 2; and PD5500 (British code). Hence the user can easily select any code material and can also create a new one. 

Features like automatic carrying forward the relevant data for newly added elements, copying input from one detail to another and 1-click sharing of data among elements aid in faster modeling.

PVElite allows users to enter data in English, SI or any user-defined units. Using the Create/Review facility users can create their own units and then change units on fly. The unique List Processor provides a concise method to review specific data sets, for example all the nozzles in the model. The fields in the List Processor tables are active, allowing user modification of the data.

The "help" facility provided with PVElite gives the user access to very specific information about the current input cell or menu selection. The help facility, details exactly what is expected, sometimes shows explanatory diagrams, and when appropriate, cites the code reference. 

The program documentation is available in a hard copy and on-line in a portable document format (PDF). Acrobat Reader software needed for viewing the on-line documentation can be installed from the PVElite CD .
