Thanks for your fast response .
Well, I modified it again and I was able to proceed up to some extent. However, even after inputting all the required data, including the shear modulus for all the rock types, when computing the fos, the following pops up " zero shear modulus at element 9" whilst I did input only 5 rock types properties.
Furthermore, the entire model becomes red when computing the displacement in any direction. Additionally, when importing other CAD files the coordinates change automatically and the model can't be seen, even though the units have been set as m,Pa, N/m3 or any.
Finally, could you please add an "Undo" option? That we will make the software a little more flexible.
Thanks
Regards
