Greetings Maria Fernanda,

You will learn a lot watching me operate the software, even if your level of English is low. If your friend can act as a translator, that would be great. I currently have no meetings on Friday, so let me know if you want to schedule a time to meet. You or I can record the meeting so you can review the video after the meeting. We shall also continue to use the Forum.

I understand you want to make a container that represents a similar stiffness to the soil. Is the idea that you want to put this container on a shaker table to simulate an earthquake?  Tell me more about the earthquake. A good way to minimize the boundary effects is to make a bigger container and limit the investigation to the soil near the center of the container, far from the walls and bottom of the container.
