SMRTool is a tool for the application of the geomechanical classification Slope Mass Rating (Romana 1993) which is it programmed in MATLAB under GNU GPL license. It allows to calculate the coefficients F1, F2 and F3 from the dip vectors of the slope (azimuth and dip) and the discontinuity (or the intersection line of planes in the case of wedge).
Automatically calculates auxiliary angles A, B and C as well as the type of failure (wedge, planar or toppling). Introducing the basic RMR as well as the type of excavation method it calculates the SMR indicating their description, stability, modes of failure and system of support recommended by Romana (1993).
As a novelty, as well as facilitate and automate the calculation, this is done according to the continuous (Tomás et al 2007) and discrete (Romana 1993) formulation.

How does it work
SMRTool aims to aid to calculate SMR geomechanical classification and its adjustment factors. These are calcualted through discrete and continous functions. The user can:
Introduce slope and discontinuity's planes, the excavation mode and its RMRb. Finally, the adjustment factors are calculated and a graphical interpretation of the auxiliar angles is provided. The user can modify the slope and the discontinuity in order to see how the auxiliar angles and the adjustment factors vary.
Introduce the slope and all the discontinuities and their respective RMRb. The program calculates all possible wedges and assigns the minor RMRb of its respective intersecting planes. Finally, it calculates all SMR values.
The last step is to generate a report in table. In Extras - Report, a file Report.tex is stored in the path where the executable file is located. It is a LaTeX file, which can be compiled with any compiler. Additionaly, you can try an example in this link: https://www.overleaf.com/2509724qcqtdx
Known issues
Latest versions of w10 included the option of changing the scale and layout in the screen settings. In some cases, the users of SMRTool could find that the GUI elements are arranged incorrectly, as shown in this figure:
As seen, the buttons and boxes are arranged in a bad way. The user cannot use correctly the software. The solution is to change the screen and layout percentage to 100%:
