Dynamic analysis-tunnel lining
Hello,
I am running a dynamic analysis model in Plaxis to find a vertical displacement of the pipeline in liquefiable soil, but it takes one day and is still running in 11.21 seconds. Is it normal for this kind of analysis in Plaxis? If so, anyone could…
[Question] How to Define Facebolt in Plaxis 2D
Hi All,
