If you already have thermochemical data-files for ChemSage, you can use them with ChemApp as well If you are using ChemSage version 4.x, you can use these data-files with ChemApp right away. If you are using ChemSage version 3.x, you need to first translate them using the program ChemFile, which is included in the ChemApp

As most third-party programs do not come in source code, they need to provide a way to link other object code to it. On Windows platforms, many commercial programs in question can access DLLs from other suppliers, in which case a DLL-version of ChemApp would be used. Other programs provide a FORTRAN or C/C++ programming

Yes, ChemApp is available for licensing. Please contact GTT-Technologies for details. ChemApp light users ChemApp light is only available for restricted redistribution with other programs (please refer to the ChemApp light license for further information (-> ChemApp documentationlight/regular). In brief, you need the regular version of ChemApp to distribute your programs for commercial purposes.
3.3 Can I distribute/sell my programs which contain ChemApp? Read More »
ChemApp is a programming tool from the area of computational thermochemistry. It is a programmer’s library consisting of a rich set of subroutines, based on the thermodynamic phase equilibrium calculation module of ChemSage (now FactSage). It permits the calculation of complex, multicomponent, multiphase chemical equilibria and their associated energy balances. ChemApp is available as object
2.1 What is ChemApp? Read More »
ChemApp is not an interactive, standalone program, it does not contain a GUI or a user menu, since it is a library of subroutines. Thus programmers who wish to add a user interface to it can add anything they want. If you are interested in a standalone, interactive program, see FactSage . ChemApp is not everything you need to perform equilibrium

ChemApp light is a free version of ChemApp, and although it is restricted in two ways compared to the regular version, it gives you almost the same functionality. For details on how the light version differs from the regular version of ChemApp, please consult the documentation (-> ChemApp documentation light/regular).
2.3 What is ChemApp light? Read More »
ChemApp light is available for download from GTT’s Technical Thermochemistry Web Page. If you have trouble downloading ChemApp light because of slow or unreliable Internet connections, let us know (support@gtt-technologies.de), we’ll provide you with ChemApp light in other ways.

Many programs, whether existing or still in the planning stage, would benefit or even need to rely on the ability the calculate chemical equilibria. Since developing such an equilibrium code, even for modest chemical systems and simple mixture phase models, is a daunting task, the need for a specialised, reliable, third-party supported code became obvious.
2.5 Why and how was ChemApp developed? Read More »
ChemApp is used in programs from such areas as process simulation and optimisation, computational fluid dynamics (CFD), solidification and casting simulation, crystal growth, kinetically controlled production processes, etc. The ChemApp web page contains examples from several application areas. In general, ChemApp can be applied in all areas where ChemSage and FactSage have already been successfully
