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

HI,
this is currently impossible. But you can overlay two regions (or elements), one corresponding to rock being excavated and deactivated and the second corresponding to lining, activated after excavation, both with different materials.

Thanks very much for your suggestion. I will try accordingly.
