The current version of the FRACOD2D code provides the basic functions needed for studying rock fracture propagation in a rock mass subjected to far-field stresses. The code is created for running on PCs with a MS Windows 95/98/NT/2000 platform. It provides an easy-to-use user's interface that enables users to monitor and interrupt the calculation. It also provides an independent pre-processor to help users in preparing the input file for a given problem.
The capacity of the current version of the FRACOD2D code is limited to about 10-15 fractures, depending upon the complexity of the fracture system and the excavation. As a general estimate, a fracture system with 10 non-symmetrical fractures will requires about 24 hours of calculation on a PC/400MHz to get a reasonably accurate prediction of fracture propagation.
