Paulin Research Group (PRG) - Finite Element Software for Piping and Pressure Vessels

ImgeGrafix Software FZCO is Paulin Research Group's representative partner covering all the countries within the Middle East and North Africa territories. Paulin Research Group (PRG) develops FEA software for the Petrochemical, Power, Offshore and Chemical Industries. Founder and President Tony Paulin, is the original author and architect of the CAESAR II® pipe stress analysis program, and established PRG to apply the latest FEA and fluid analysis technology to the piping and pressure industries. PRG has conducted numerous leak and fatigue tests since 2001 and the results are incorporated into our software to make plant components more dependable and increase plant safety. PRG's goals are to provide updates to an industry that relies on technology that is often more than 25 - 75 years old.

FE/Pipe v5.0

FE/Pipe is the most mature and comprehensive product offered by Paulin Research Group. The application areas are a superset of the PRO series with additional functionality. FE/Pipe is a finite element analysis specifically designed for use in the pressure vessel and piping (PVP) industry. What separates FE/Pipe from the rest of the general FEA tools is its ability to rapidly construct PVP geometries and produce ASME stress reports. FE/Pipe makes modeling typical pressure vessel and piping geometries faster and easier than is possible with general FEA tools due to the parametric design philosophy. The parametric approach used in FE/Pipe permits even novice finite element analysts to construct accurate models using only dimensional input. FE/Pipe automatically creates the model geometry, element mesh, applied loads, and boundary conditions based on standard dimensions. Results are presented in terms of ASME requirements instead of generalized stress tensors and stress intensities as would typically be found in general FEA tools.

AxiPRO v2.7and NozzlePRO v7.5

AxiPRO and NozzlePRO simplify the application of finite element technologies by defining a subset of problems by component and codifying many of the decisions that need to be made in FE/Pipe based on component geometry and loading.

Template Selection
Meshing to Ensure Convergence
Surface Definitions
Boundary Conditions
Modeling of flange nonlinearities (including gasket)
Automated results plotting

Very simply, AxiPRO and NozzlePRO are designed to be easier to use than FE/Pipe where FE/Pipe maintains the most exhaustive feature set. AxiPRO and NozzlePRO call FE/Pipe in the background. AxiPRO and NozzlePRO licenses are included with FE/Pipe.

MatPRO v2.0

MatPRO is an exhaustive database of ASME material properties that can be used with PRG and third party software products. In addition to providing material properties to PRG products, MatPRO also includes calculators for high temperature analysis, fatigue allowable comparisons and fitness for service evaluations. A MatPRO license is included with each FE/Pipe license.

MeshPRO

MeshPRO provides an interface between AutoCAD and FE/Pipe. It is particularly useful when a geometry cannot be easily modeled with one of the FE/Pipe templates. MeshPRO allows Axisymmetric, Shell and Brick models to be created and modified in AutoCAD, and then analyzed in FE/Pipe. A MeshPRO license is included with each FE/Pipe license.

PlasPlot

PlasPlot is a companion utility to FE/Pipe that periodically queries a running nonlinear model and displays the current state of the analysis including the convergence trend. PlasPlot is included with FE/Pipe.

StressPlot

StressPlot is a general ASME codes stress calculation utility. StressPlot can be used to read raw nodal stress data and process the stresses to linearize through the wall of any geometry per guidelines in WRC 429. StressPlot is included with FE/Pipe.

FE107

FE107 is a load analysis program for openings in calculating local stresses in spherical and cylindrical shells subject to external loadings. FE107 offers a subset of the analysis capabilities of NozzlePRO with a fraction of the effort.

BOS Fluids v4.3

BOS Fluids is the engineering software package that analyzes fluid transients in pipe systems and relates this information back to the mechanical piping system transferring the fluid.

Splash

Splash is a 2D Free-Surface CFD calculator that lets the user pick a predefined geometry, or allows him to define his own. The free surface fluid can be exposed to initial velocity loads, (slugs), periodic loads, (pitch and roll), or seismic loads, (transient time history analysis).
