Update to SimSci Licensing Options

Dear SimSci Software User, 

This post is to provide an update on the licensing and security options from Flexera Software, who produces the security software that SimSci software products use for LAN, WAN, and Token Licensing. Flexera Software FLExNetPublisher (FNP) 11.11 and (FNP) 11.12 have reached the end of limited Lifecycle support.

In an effort to support our customers going forward, SimSci is supporting now the latest version of FlexNetPublisher, 11.14.  The SimSci team is implementing the following plan:

1.       Existing FNP 11.11 and FNP 11.12 security licenses will be upgraded the next time they are renewed to FNP 11.13 or FNP 11.14. However, we do recommend that you upgrade at your earliest opportunity to avoid any potential problems.  
2.       Older FLEXlm licenses will continue to work, however, if they stop working before the renewal period, they must be upgraded to FNP 11.13 or FNP 11.14.
3.       Future installations of SimSci software will allow FNP 11.13, FNP 11.14 and respective TOKEN versions, and USB security options. 
4.       The latest server software install and a retrofit package to upgrade all your SimSci software to use FNP 11.14 can be downloaded from the Support Site.  
5.        Any customer migrating to Windows 10 will need to upgrade to FNP 11.13 or FNP 11.14 as previous versions of the server do not install in Windows 10. 

We appreciate your patience through the migration and will do our best to minimize the impact on your use of our products. Please contact technical support if there are any problems.

New Capabilities in SimCentral Simulation Platform 2.0

SimCentral Simulation Platform 2.0 delivers these new capabilities:

For Simulation Builders:

  • Faster and more reliable editing of curve data.
  • Improved the way Snapshot variables are saved in Snapshots to support upward compatibility.
  • There are now Torque and Acceleration variable types.
  • Mole fractions may be in ppm.

  • Typical Connection Models can be a stream for process simulation, or a pipe for fluid flow simulation.


  • Thermo Data Manager (TDM) integration, DETHERM PPDX support, Grayson-Streed correlation, Racket liquid density method, COSTALD liquid density method, Vapor-Liquid-Water (VLWE)

Control Library:

  • The PID controller now has mole flow and volume flow options.

Cooling Water Library:

  • There is now a Reducer / Enlarger model. The Pump now has a Net Positive Suction Head calculations for NPSHR (required) and NPSHA (available); calculate efficiency from the pump performance curve.

Flare Library:

  • The Pipe is the default Connection Model; PipeRig is optional The Pipe calculates density times velocity squared variable called rhov2, commonly used for flare pipe sizing. If the Pipe Service parameter is set to InletPipe, the pressure drop is calculated to check the 3% rule, but is not applied to the relief valve inlet per API 521 practice. PipeRig uses equal length segmentation as a more reliable default setting, especially for low or zero flow and includes no-slip holdup in each segment.
  • The Stack calculates Thermal Dosing Units (TDU) from Health and Safety Laboratory (HSL) report “Human Vulnerability to Thermal Radiation Offshore”.
  • There is a FlowPort to FlarePort converter to create simulations consisting of both Process and FlareLib library models.

Steam Library:

  • The Pump has a Net Positive Suction Head calculations for NPSHR (required) and NPSHA (available). The Pump can calculate efficiency from the pump performance curve. PipeRig uses equal length segmentation as a more reliable default setting, especially for low or zero flow.

Process Library:

  • There is a new Distillation Column and a three phase separator.
  • Drum model has a non-equilibrium option with separate vapor and liquid holdups.
  • Pump has a Net Positive Suction Head calculations for NPSHR (required) and NPSHA (available). The Pump can calculate efficiency from the pump performance curve.
  • There is a new Recycle model that helps with some hard to converge recycles.

Custom Transient Flow Library:

  • For sources, you can enter vapor fraction for vapor pressure calculations to perform column separation when the piping pressure is lower than the fluid vapor pressure.
  • Valve model can take input from the PID and other models in the Controls library.
  • New warnings for heat exchanger tube rupture.
