Back to HomeThe FRACOD2D code is created as an executable file (Fracod2D.exe). To start the code FRACOD2D, simply double-click the executable file in Windows, a dialog menu will appear on your screen. You then need to open an input data file or a FRACOD2D save file, by using the open file options. If you are starting a new problem, you need to load a input data file which has already been prepared either by using a text editor or by using the model design function provided in the code (see Appendix I). If you are restarting a problem which has previously been run and saved, you then need to load the saved file (*.sav). FRACOD2D will automatically detect whether the file you are loading is an input data file or a save file. Once a calculation has started, it will continue until it is interrupted manually, or the defined cycles finished, or no more fracture propagation is found. During the calculation, the instant geometry of the modelled fracture network is always shown on the screen so that any growth of the fractures can be monitored. The fractures are plotted in different colours to distinguish whether the fracture surfaces are in elastic contact, open or sliding (the colours can be specified or changed by users). When a calculation is completed or is interrupted, a number of screen commands are available to plot the stress/displacement or to change the parameters etc. These commands are provided as icons on the program window and can be easily activated by clicking the mouse. The key functions of the available screen commands are shown below.
