water level in Plaxis 3D

Question

Hi all, 
 I'm starting to learn Plaxis 3D and i'm confusing how to use "create water level" option and I'm unable to find any videos relating that. Can anyone please explain? 
 Thanks,

Dear Nitha, 
 The principle of setting the water level is essentially the same as in 2D. In PLAXIS 3D Tutorial in Example #7 you can find one of the variants: https://communities.bentley.com/products/geotech-analysis/w/plaxis-soilvision-wiki/45578/plaxis-3d-tutorial-07-rapid-drawdown-analysis 
 Also you can watch our video about this Tutorial: https://www.youtube.com/watch?v=ZCdJuBk3a5Q 
 The video is in Russian, but you can use YouTube English automatic translation subtitles in the settings. 
 Also I add some screenshots from our presentation (sorry, it is also in Russian, but I hope everything is clear):

Dear Nitharshan , 
 In this case you need to create at least 12 points: &mdash; 4 corner points with coordinate Z = external water level (origin water level); &mdash; 4 points closer to the pit with the same coordinate Z; &mdash; 4 points even closer to the pit, but with coordinate Z = desired water level (usually the bottom level of the pit or lower).

Sorry for the bad screenshots. 
 If you want to set dewatering in the excavation, sometimes deactivated clusters inside the excavation (excavated soil) are set as Dry. The water level can be left at the initial level. In this case we should get a similar result. Moreover, this method is much easier to set.
