- Removed VSTA and VBA 6.5, and implemented VBA 7.1 - Simplified the .msi and .exe CHEMCAD installation process
- Implemented Schultes 1999 as a packing method for mass transfer column sizing and rating
- Improved the enthalpy calculation for high-temperature, low-pressure water properties
- Corrected an issue with mass balance in the Solid Washer UnitOp
- Corrected an issue with incorrect reporting units for slurry density
- Corrected an issue with Excel reports failing to separate columns of data
- Corrected an issue with the VBA command PutStreamInCurUserUnitByID
v6.4 [Sep 1, 2011]
State-of-the-art licensing tool, RMS License Manager, which expands CHEMCAD's commuter licensing capabilities. New Thermo Acceleration operating mode, which can help speed calculations for complex simulations. Improved dynamic column performance. Enhanced user-defined component database, which enables users to specify electrolyte density, viscosity, diffusivity, Henry's constants, and BIPs. BIP regression from partial pressure data. Improved convergence for multiple solid electrolyte systems. Capability for simultaneous heat transfer and mass transfer models in distillation columns. Capability to run Excel Data Maps for each time step in dynamics mode. New section on the Topology Report that lists stream and UnitOp relationships, such as controllers, stream references, streams copied from another flowsheet, and META units. Improved convergence for node flowsheets where some UnitOps are near critical flow.
