Topic: Change Element's Material at Given Time Steps
I would like to simulate the excavation process of a tunnel. In the proposed case, there are two separate processes, i.e. excavation and lining. The elements to be excavated are soil/rock including lining elements. After excavation, the lining elements (original soil/rock element) will be activated using activityltf. However, I didn't find how to change the materials from soil/rock to lining. Is it possible to change the element's material at given time steps?
Thanks and regards,
Ding
