The water level is 11m above the ridge. In the construction state, the water is drained 4m around the tunnel. I have tried to model this with a dry zone around the tunnel and defined the behaviour of the tunnel interface as &quot;head&quot;. Unfortunately, the model does not work. I get the following error message: &quot;Load advancement procedure fails&quot;. Can you tell me whats the best way to simulate the drainage and the drained condition in Plaxis 2D.&nbsp;</p> <p>Thank you in advance.&nbsp;</p> <p><img style="max-height:240px;max-width:320px;" src="/resized-image/__size/640x480/__key/communityserver-discussions-components-files/343671/pastedimage1690960005167v1.png" alt=" " /></p><div style="clear:both;"></div>Ask A Question Ihttps://communities.bentley.com/achievements/460ac7df-7ccc-4c42-a204-9e05eef3be09Tue, 25 Jul 2023 04:42:17 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:cdb961e8-6cff-4b71-ac10-1188487f0376Ask a question in a forum.
