What's Changed

In TESPy version 0.11.0 a major refactoring was applied to the presolving and the solving. Initial guesses, numerical stability of the solver and debugging models are improved. A block decomposition of the numerical problem allows to simplify the solving process and provide exact hints on model failures.

tespy - TESPy version 0.9.0

TESPy version 0.9.0 was in preparation for quite a bit and comes with a big refactoring of the back-end. The most important features are:

Drastically (!) improved debugging capabilities of you model
PowerConnections and power related components (motor, generator, powerbus, powersink, powersource) for explicit modeling of mechanical and electrical power as well as heat flows.
Improved preprocessing making initial solves more resilient towards starting values

For users of standard components of tespy API changes mostly apply to the UserDefinedEquation. If you are using custom components, you have to make more adaptions to your models to make them work again. For an overview of the changes and information on how to use the new features please check out the docs: https://tespy.readthedocs.io/en/main/whats_new.html.
