Object oriented framework for multiphysics analysis

The present work shares the new features included in the open source software INSANE (Interactive Structural Analysis Environment) for managing and solving multiphysics engineering problems. The implementation described in this paper focuses on the thermomechanical problem when the material’s physical properties are temperature dependent and the problem is analyzed accordingly to the Finite Element Method (FEM). The suggested framework is based on a new entity, called Simulation Manager, responsible for setting up the analysis parameters for each physics, for controlling the solution process and for managing the data to be transferred from one analysis to the other. Both analysis are carried out using the same discrete model. Since the software is written according to the Object Oriented Programming, the existing resources for solving single-physics problems could be combined to minimize code repetition. The implementation was tested and validated by solving problems whose analytical solutions are available in the literature.
