Predict 6.1 Overview: What's New in PREDICT 6.1?
Predict 6.1 encapsulate state-of-the-art corrosion prediction technologies, and includes critical, hitherto unavailable data on various aspects of corrosion prediction of carbon steels for production and transmission applications. Predict 6.1, a by-product of years of corrosion research and modeling, incorporates a completely re-worked and enhanced user interface to provide access to a comprehensive knowledge base on corrosion decision-making. It is an easy-to-use tool that integrates effects of a complex set of environmental parameters on carbon steel and low alloy steels to provide corrosion rate quantification based on extensive JIP data and laboratory evaluation, as well as data from literature and field experience.
Major aspects of Predict 6.1 enhancements include:
Full compatibility with Windows 7 32-bit & 64-bit operating systems.
Ability for users to incorporate results (wall shear stress and flow regime) from a third party flow model.
New and more accurate pH prediction and ionic strength model that accounts for appropriate ionic and phase behavior effects of most common acid gas components (H2S, CO2) as well as relevant anionic and cationic species.
Ability for user to choose the balancing ion. User can choose balance type which suites to his requirements.
Ability to provide two different water analyses for inlet and outlet conditions (or wellhead and bottomhole conditions).
Improvised saturation pH calculations. New results screen helps users understand scaling in system with details about FeCO3 and FeS scale formation.
Enhanced usage and ease of incorporating water production data. Users can now provide liquid water flow rate in system and get detailed results on predicted dew point temperature and water condensation at intermediate points in pipeline/tubing.
Ability to enter gas flow rate at actual conditions (at operating conditions).
Ability to model liquid only streams without data for gas partial pressures. User can enter CO2 & H2S aqueous data in ppm and Predict 6.1 estimates equilibrium partial pressures from dissolved gases.
Ability to evaluate the pitting model saturation calculations for FeCO3 scaling and saturation pH calculations for predicting FeCO3 scaling.
Predicted Time To Failure plot available for Inlet and outlet (wellhead and bottomhole as well)
A more informative cost module with wide coverage of different cost components.
Enhanced exporting capabilities.
Improvised analyses capabilities with Multi Point Analysis and Expert Multi Point Sensitivity Analysis tools that help users identify safe operating envelopes.
Tips and suggestions to assist users in performing tasks, understanding relationships and evaluating parametric effects.
A completely re-implemented and re-worked software interface, including the ability to automate analyses for multiphase production systems and flowlines.

Improvements for Ver 20.00 November 23, 2017
• Add new features in BePerf for fixed-lobe and tilting pad journal bearing design:
1) Parametric study 2) Design Comparison. See Ver_20_ReleaseNotes.pdf.
• Add option to add/modify more lubricants into the oil library. Note that the first
33 lubricants cannot be changed. But users can add more lubricants into the
library. See Ver_20_ReleaseNotes.pdf.
• ThrustBrg: to be consistent with BePerf, the Case number in ThrustBrg starts
from 1 instead of 0.
• ThrustBrg: Fixed a bug in the pressure plot color legend, also add numeric scale
on the legend.
• In Rotor, add capability for the rotating bearings (mainly for turbochargers, see
example Ch_6_FRB_4DOF_Non-Circular_Inner_Film.rot),
or rocking bearings (for ship applications, see example V20_sund_ship.rot and
Ship_Rocking_Animation….gif animation files).
• Transient Analysis in Frequency domain, the initial condition for the high speed
point uses the final condition from the previous speed point.
• In the Transient Analysis, the integration time and time step are important for the
FFT plot, therefore, add “Suggested Time Step” feature for the integration time
and time step. In some highly non-linear cases, if the suggested time step could
not converge, then use smaller time step. Try new time step = old time step / 2.
• Add velocity and acceleration in the FFT displays.
• Improve Whirl Speed and Stability Maps – Magenta color for the forward modes,
Green color for the Backward modes, Blue color for the mixed modes. Also add
the option to plot the forward and mixed (if exists) modes only. Since the forward
modes in most cases are the concerns, not the backward modes.
• Add damping factor vs. frequency ratio (API 610) in the PostProcessor for the
Whirl Speed and Stability Analysis.
• Add Bearing Type 15 in Rotor. This option allows the Rotor and BePerf be fully
integrated. This is for the linear analysis only. For Non-Linear analysis, use Type
13. Using Type 15, the unit system between rotor file (rot) and bearing file (LDI,
or TDI) can be different, although consistent unit system is recommended. But
they can be different.
• In Rotor Program, any files associated with the ROT file, such as the bearing
files, foundation file, and torsional excitation torque files, if they have the same
path name with the rot file (i.e., they are located in the same folder with rot file),
the path name will be removed for simplicity and easy portability. The Rotor
program will also double check the existence of these associated files. If they are
not found under their specified path, then the rot path name will be used for
another try.
• Add new analysis types 12, 15, 16, 17, 18, 19, and 20.
• Add Design Comparison in Rotor – Compare different designs.
1. Compare two different (.rot) files
2. Same rot file, but different bearing files
3. Same rot and bearing files, but different bearing variables
• For more information and examples, See Ver_20_ReleaseNotes.pdf.
Improvements for Ver 19.02 May 9, 2017
• Improve the Text Output Format (*.OU2 and *.OU4).
• Correct some spelling errors.
• Fix a bug existed in Ver 19.01 in the heat balance calculation for the Fixed Lobe
Bearing Type with Advanced Features ON.
• Fix a graphic error in the torsional mode shape plot when Rigid Link in the Shaft
Elements tab is checked to connect two shafts.
• Batch mode examples for verifications and future expansion – see
BatchRunRotor.bat, BatchBePerfTpj.bat, BatchRunLobeDNF.bat,
BatchRunReynolds.bat, and BatchRunExample.bat
Improvements for Ver 19.01 January 7, 2017
• Use the latest Safenet (Software Protection Software) drivers.
Improvements for Ver 19.00 January 1, 2017
• Allows dot (“.”) and white space (“ “) in the file and path name.
• Speed dependent bearing coefficients can be either spline interpolation or linear
interpolation in the Rotor program. Spline function was used before Ver 19. The
Bearing coefficients after the interpolation are printed in the text output file.
• Critical Speed Analysis – for speed dependent bearing coefficients, the stiffness at
the last speed point was used. Now, the speed point can be specified. If not
specified (i.e., zero value), then the last speed point is used as before. The
damping effect can also be included if the bearing dynamic stiffness is desired. If
the specified rotor speed is close to the critical speed, the result and mode shape
will be more accurate.
• Add more model checking features to avoid any mistakes in building the rotor

Improvements for Ver 20.00 November 23, 2017
• Add new features in BePerf for fixed-lobe and tilting pad journal bearing design:
1) Parametric study 2) Design Comparison. See Ver_20_ReleaseNotes.pdf.
• Add option to add/modify more lubricants into the oil library. Note that the first
33 lubricants cannot be changed. But users can add more lubricants into the
library. See Ver_20_ReleaseNotes.pdf.
• ThrustBrg: to be consistent with BePerf, the Case number in ThrustBrg starts
from 1 instead of 0.
• ThrustBrg: Fixed a bug in the pressure plot color legend, also add numeric scale
on the legend.
• In Rotor, add capability for the rotating bearings (mainly for turbochargers, see
example Ch_6_FRB_4DOF_Non-Circular_Inner_Film.rot),
or rocking bearings (for ship applications, see example V20_sund_ship.rot and
Ship_Rocking_Animation….gif animation files).
• Transient Analysis in Frequency domain, the initial condition for the high speed
point uses the final condition from the previous speed point.
• In the Transient Analysis, the integration time and time step are important for the
FFT plot, therefore, add “Suggested Time Step” feature for the integration time
and time step. In some highly non-linear cases, if the suggested time step could
not converge, then use smaller time step. Try new time step = old time step / 2.
• Add velocity and acceleration in the FFT displays.
• Improve Whirl Speed and Stability Maps – Magenta color for the forward modes,
Green color for the Backward modes, Blue color for the mixed modes. Also add
the option to plot the forward and mixed (if exists) modes only. Since the forward
modes in most cases are the concerns, not the backward modes.
• Add damping factor vs. frequency ratio (API 610) in the PostProcessor for the
Whirl Speed and Stability Analysis.
• Add Bearing Type 15 in Rotor. This option allows the Rotor and BePerf be fully
integrated. This is for the linear analysis only. For Non-Linear analysis, use Type
13. Using Type 15, the unit system between rotor file (rot) and bearing file (LDI,
or TDI) can be different, although consistent unit system is recommended. But
they can be different.
• In Rotor Program, any files associated with the ROT file, such as the bearing
files, foundation file, and torsional excitation torque files, if they have the same
path name with the rot file (i.e., they are located in the same folder with rot file),
the path name will be removed for simplicity and easy portability. The Rotor
program will also double check the existence of these associated files. If they are
not found under their specified path, then the rot path name will be used for
another try.
• Add new analysis types 12, 15, 16, 17, 18, 19, and 20.
• Add Design Comparison in Rotor – Compare different designs.
1. Compare two different (.rot) files
2. Same rot file, but different bearing files
3. Same rot and bearing files, but different bearing variables
• For more information and examples, See Ver_20_ReleaseNotes.pdf.
Improvements for Ver 19.02 May 9, 2017
• Improve the Text Output Format (*.OU2 and *.OU4).
• Correct some spelling errors.
• Fix a bug existed in Ver 19.01 in the heat balance calculation for the Fixed Lobe
Bearing Type with Advanced Features ON.
• Fix a graphic error in the torsional mode shape plot when Rigid Link in the Shaft
Elements tab is checked to connect two shafts.
• Batch mode examples for verifications and future expansion – see
BatchRunRotor.bat, BatchBePerfTpj.bat, BatchRunLobeDNF.bat,
BatchRunReynolds.bat, and BatchRunExample.bat
Improvements for Ver 19.01 January 7, 2017
• Use the latest Safenet (Software Protection Software) drivers.
Improvements for Ver 19.00 January 1, 2017
• Allows dot (“.”) and white space (“ “) in the file and path name.
• Speed dependent bearing coefficients can be either spline interpolation or linear
interpolation in the Rotor program. Spline function was used before Ver 19. The
Bearing coefficients after the interpolation are printed in the text output file.
• Critical Speed Analysis – for speed dependent bearing coefficients, the stiffness at
the last speed point was used. Now, the speed point can be specified. If not
specified (i.e., zero value), then the last speed point is used as before. The
damping effect can also be included if the bearing dynamic stiffness is desired. If
the specified rotor speed is close to the critical speed, the result and mode shape
will be more accurate.
• Add more model checking features to avoid any mistakes in building the rotor
model. An element L/D checking feature can be pre-specified in the Preference
Settings – Model Display Settings.
• Model Flipping (Reversing) – allows to flip the rotor model (left to right)
• Models Combining (Merging or Appending) – allows to combine tow model files
into a single file. This allows users to build the complicated model with multiple
rotors one rotor at a time.

initially designed for the lateral vibration only.

be associated with the curve color.
