Dear Roozbeh
I have tried the software, version 1.07, and it works in the sense that the results are in accordance with the analytical formulation. I have tried a simple square foundation on an elastic material.
In my opinion, and if you want, I could help you the next step should be:
a) it could be very useful if flow modelling could be developed
b) importing dxf (maybe with only one layer as per SAP so the script shall be easier) or meshed elements (in this case I could suggest to see this webpage
http://www.robertschneiders.de/meshgeneration/software.html)
c) improve the structural elements in order to carry out real soil structure calculations. In this sense, it could be important if we could take into account the non-linear behavior of beam/cables and the study of their connections (pin/hinge/springs).
d) the triangular mesh is not always adequate, maybe you should open the possibility to create some quadrangular mesh elements to reach a major robustness in some calculations as tunnels.
you have done a very good job and I am very keen to see the new releases,
The window is very simple and, in my opinion, you are in the right way,
Let me know if you need my help,
Good Luck,
Best regards,
Cosimo
