Dear All,
I am modeling a tunnel under the water table. The analysis includes the hydrostatic solution without water flow analysis. So, I considered the water table and its density in the model without CONFIG FLUID and put the other commands like a dry analysis with Mohr Model. However, when I controlled the contour of the displacement after 1m of the excavation, the displacement in the tunnel’s boundary was considerably high in comparison to the zones which located immediately behind the boundary (maybe 2000 mm to 10 mm). How can I fix this problem?
Thanks
