TIL Suite – Simulates thermal systems

TIL Suite is suitable for the stationary and transient simulation of freely configurable thermodynamic systems. Thanks to the substance property library, TILMedia – a component of the TIL Suite – system simulations can be performed extremely quickly and accurately. The individual models in TIL are described using the modeling language Modelica. However, the use of these models is not limited to Modelica simulators; other simulation environments can also be used thanks to code-export and model exchange functions.

TISC Suite – Software package for coupling simulation tools

TISC is a co-simulation environment that makes it possible to connect calculation models across more than one simulator and couple these into one system and simulation. The TISC Suite software package includes several applications and interfaces to simulation programs and hardware that enable the control of the co-simulation and data exchange between the individual simulation models.

Simulator Suite – Simulation and evaluation of models

The Simulator Suite enables a user-friendly and efficient evaluation of models with a focus on the FMI standard. Models can be simulated in well-known applications like Excel or LabVIEW as well as integrated into existing software via SDKs in C++ and Python. In addition to supporting the FMI standard, Dymola models can also be simulated directly. Extensive configuration possibilities and a specialized solver technology allow the high-performance evaluation of even complex thermodynamic systems.

Optimization Suite – Model-based optimization

TLK's Optimization Suite is an environment for model-based design optimization, model fitting and control optimization, specialized for thermal systems. Stationary and transient optimization tasks as well as various optimization algorithms are supported. Our Optimization Suite provides a python-based high-level interface for model evaluation (setting optimization parameters, calculation of cost function, constraints and jacobians) by performing transient or steady-state simulation internally.

ModelFitter – Parameter fitting and model analysis

The ModelFitter is a software tool for the automated fitting of model parameters to an existing database. The ModelFitter can also be used for design of experiments (DOE). The used Levenberg-Marquard algorithm in combination with the efficient evaluation routines of the TLK Software Framework offers the possibility to easily adapt even dynamic, highly nonlinear models. The models are addressed via the FMI standard. A ready-to-use Excel tool is available as a user interface.
