July 4th, 2011· This version has some minor corrections to third-body reactions with enhanced body coefficients.
August 30th, 2010· The DASPK integrator that can be invoked through "-INT:5" switch. This new integrator can handle tough combustion models that can break the other integrators. In some cases speedups of over 100 times (10,000%) are possible. For example, the Chlorate-Iodine sample reactions model takes about 3 minutes to run utilizing "-INT:1", but finishes under 2 seconds with the DASPK integrator. Note that it is not a silver bullet and it is still recommended to stick with the first integrator, "-INT:1", then followed with the DASPK integrator, "-INT:5", if continued problems persist, then followed by #4, #2 and #3 integrators. See manual for further details.
· Jet Propulsion Laboratory 4-parameter fit to the Troe expression ( see section 2 at http://jpldataeval.jpl.nasa.gov/download.html ) chemical kinetic forms are now supported
· Various bug fixes
· The chemkin to Kintecus converter tool and the other tools have been recompiled and should run under Windows7 as well as Windows Vista/XP.
September 7th, 2009· Kintecus V3.962 has been released to correct the problem with reactions that have more than four products.
September 7th, 2009· Some international users who have installed a non-English version of Windows98/XP/Vista were not able to run Kintecus because Kintecus could not generate a unique computer ID for their computer. This should be fixed with Kintecus V3.961.
July 19th, 2009· Support for up to 10 products. You can now do some serious global reaction modeling.
· Weights/standard deviation support for experimental data during fits / regression.
· All you have to do is specify the weight or standard deviation in parenthesis after your datapoint(s).
· Special Species Directives that will significantly help in tough regression fits of
· experimental data that is a composite of multiple species. This feature has many important uses in regression and data analysis. For example, you are monitoring four wavelengths for absorbance, but each wavelength contains the absorbance from another species, so one cannot extract the concentrations from a kinetic one because one does not know how much "contamination" from another species absorbance, so you could not perform any data analysis with such an experiment. Now you can.
· The ability to scale the energy source/sink with respect to changing volume in a constant pressure run.
· Now specify a table (can be an Excel Worksheet) containing variable time steps for normalized sensitivity analyses. This is useful for mechanism reduction and elucidation.
· Actually, you can do this with any version of Kintecus, but you had to crunch the numbers on the command line and could only do about 30 variable steps. Now you can do up to a thousand and have them all specified and easily seen/plotted on an optional Excel worksheet.
Bugs Corrected:
· There is one notable bug in Kintecus 3.95 or below. If you are utilizing Normalized Sensitivity Analysis (NSA) with no temperature program and/or no thermodynamics turned on (via the –THERM switch) AND you are utilizing non-zero Arrhenius parameters (not just a rate constant), then those reactions with non-zero Arrhenius parameters with always have a Normalized Sensitivity Analysis coefficient of zero (0). Kintecus V3.96 has this bug corrected.
· Again, this bug is fairly limited in scope as most users that use NSA either have thermodynamics on, or are only utilizing rate constants, k (not A, m and Ea), in their model with no thermodynamics.
August 4th, 2008· Enhacements and bug fixes
December 19th, 2006· the ability to perform complex hierarchical cluster analysis on temporal concentration profiles of the network with/without experimentally obtained temporal concentration profiles
· Several more reaction types
· The True Global Equilibrium feature is more robust in
· solving systems near or at plasma temperatures and/or
· multi-phasic systems.
· Coupling of combinatorial scanning with output files such as system thermodynamic output, rate fluxes, species fluxes, cluster analysis, Jacobian output, eigenvector/eigenvalue output of the Jacobians.
