NeqSim 2.0.1

Added new PVT lumping method. Added possibility to set composition of plus fluid.

NeqSim 2.0

Updates in NeqSim 2.0 are:

• Improved speed and stability of algorithms (TPflash, phase envelopes)
• Added GERG-2008 for calculation of gas density
• Various updates in process simulation models (compressors, recycle, mechanical design)

NeqSim 1.2

Added GERG 2008 reference EoS

NeqSim 1.1

Updates in release 1.1 (05/08/2019):

• improved stability of TP, PH and PS flash algorithms
• improved stability of phase envelope calculations
• pressure correction to viscosity model of aqueous phase (method of Lucas (1981)
• updates to pure component parameters/binary interaction parameters of some components
• a number of minor improvements to the code

API of NeqSim v1.1 is fully compatible with v1.0.

v1.1 release of NeqSim on Github. The NeqSim-1.1-shaded.jar includes NeqSim-1.1.jar as well as all third party libraries used by NeqSim.

By default NeqSim uses a fully functional embedded Derby parameter database. The neqsimthermodatabase.sql can be used to create a parameter database for neqsim. The database need to support JDBC (e.g MySQL, H2, Derby, MSAccess, etc.). See the Wiki for how to set up a new database.
