Edition 3.6 (release date: May 1st, 2003)

  1. Descriptions for the following new subroutines have been added: TQCEN, TQCENL, TQGTHI, and TQGTED.

  2. Table 19: added new option 'AP'.

  3. In Table 2 and 9, the solution models HTSZ, HTWZ, HTDZ, and PIHZ have been added.

  4. Added a note to Chapter 1.7 about all Windows versions of ChemApp requiring a hardware key (dongle) as of V5.0.0.

  5. Chapter 1.10 (ChemApp best practices) has been added.

Edition 3.5 (release date: July 1st, 2001)

  1. Descriptions for five new subroutines have been added that were introduced with ChemApp V3.3.1 and relate to sublattice phases: TQINLC, TQGNLC, TQNOSL, TQNOLC, TQGTLC.

  2. The data-file SUBL-EX.DAT (see Chapter 1.12.7) is now part of the ChemApp distribution. Its main purpose is to serve as an example data-file for the demonstration of the various sublattice model subroutines.

  3. Descriptions for the subroutines TQOPNA and TQOPNB have been added, those for TQOPEN, TQCLOS, TQRFIL, and TQRBIN have been updated accordingly. The Chapters 1.11.2 and 1.11.3 have been added to illustrate the use of the file I/O subroutines.

  4. The use of TQOPNA, TQOPNB, TQOPEN, and TQCLOS intead of OPEN and CLOSE is now also recommended and supported for FORTRAN programs. While this is not necessary for FORTRAN programs which are linked to ChemApp in form of a static library, it is required in many cases where ChemApp is used in form of a DLL. The documentation of the subroutines involved has been updated accordingly. Since these subroutines are now part of the ChemApp core code, the associated error messages 901 and 902 have been changed to 107 and 108.

  5. A short text on user-defined models (Chapter 1.11.1) has been added.

  6. In Table 2 and 9, the solution models SITZ, SUBE, and SUBG have been added. The models RKXP, MARP, KKOP, and KKXP are no longer available as of ChemApp V4.0.0, their entries in the tables have been deleted.

  7. Descriptions for the new subroutines have been added that are related to transparent file handling: TQGTID, TQGTNM, TQGTPI, TQOPNT, TQRCST, and TQGTRH. Chapter 1.11.4 has been added.

  8. A description for the new subroutine TQUSED has been added.

Edition 3.4 (release date: March 22nd, 1999)

  1. Table 19: added missing option 'VM' for variable Volume/amount unit. All other variables of the same group ('CPM', 'HM', 'SM', and 'GM') should be labelled per amount unit instead of per mass unit too.


Edition 3.3 (release date: February 3rd, 1999)

  1. A note has been added to the description of TQCSC that it is not possible to change the system components if the system (i.e. the data-file loaded) contains one or more phases modeled using the SUBO (Two-sublattice order/disorder) formalism.

  2. A note has been added to the description of TQCSPC to explain some restrictions that apply to changing the status of phase constituents.

  3. Table 13: option 'A': For a precipitation target, VAL must be < 0, not <= 0.

Edition 3.2 (release date: January 27th, 1999)

First printed and distributed edition for ChemApp versions 2.0.2 and later.
