I have tried python to set void ratio to be 0.3. The command line also confirms the initial void ratio of 0.3. However, in the material sets tab, the void ratio is still 0.5 (the default value). Any one knows solution?
Dear Chao,
You are right to be confused with this. PLAXIS internally stores the porosity but exposes the void ratio as a parameter in the GUI.
You should change the porosity instead, using the void ratio value you have using the following equation: n = e / (1 + e)
Thank you very much. This is really helpful.
