Abstract
This work describes our efforts towards building an object-oriented software framework for Interface Stress Element Method (ISEM), a newly developed numerical method for discontinuous and fracture problems. Based on the improved Interface Stress Element Method and object-oriented technology, we recognized major objects in ISEM and their interrelations. Then the class hierarchy, modules organization and data interfaces scheme were presented. We also addressed implementation issues and main features of this framework, which integrated a solver, a post-processor, a preprocessor and a model data converter. Numerical examples demonstrated that this system works well, which is a good starting point for further development.
