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.
Dear Iojain,
You can make a parametric study on the void ratio that you are interested in, but in your script use an equation to convert the void ratio to the porosity each time.
In this way, the command runs as expected and your data continues being related to the void ratio.
