TQ-Interface, short for Thermodynamic Calculation Interface, is designed for time-critical, computationally intensive application software that is most likely but not necessarily written in Fortran. It constitutes a collection of Fortran subroutines and functions supplied in the form of a DLL (Dynamically Linked Library). There are also C functions matching all the Fortran subroutines in order to facilitate users who wish to program in languages other than Fortran.
TQ-Interface is successfully used in the MICRESS™ software package (developed by ACCESS e.V., in Aachen, Germany), for simulation of microstructural evolution in multicomponent alloys using a phase-field approach.
TQ-Interface is only available on Windows and Linux platforms.
