The goal of the project is to develop new discretization methods forthe computer simulation of coupled thermomechanical problems. Thefocus is on the development of thermodynamically consistent (TC)methods. TC methods are capable of preserving major structuralproperties of the underlying continuous problem. In particular, TCmethods aim at the satisfaction of both the first and second law ofthermodynamics. In addition to that, they exactly satisfy the balancelaw for angular momentum. Due to their structure-preserving features,the newly envisaged TC methods are expected to yield improvednumerical stability, robustness and accuracy when compared tostandard methods.

该项目的目标是开发新的离散化方法，用于热力耦合问题的计算机模拟。重点是发展化学相容性（TC）方法。TC方法能够保持基本连续问题的主要结构性质。特别是，TC方法旨在满足热力学第一和第二定律。除此之外，它们完全满足角动量的平衡定律。由于它们的结构保持功能，新设想的TC方法预计将产生改进的数值稳定性，鲁棒性和准确性相比，标准方法。
