https://communities.bentley.com/products/geotech-analysis/f/forum/240002/derive-the-distribution-of-forces-in-a-volume-element-for-all-instants-of-timeHello, everyone, I am interested in deriving force-displacement or moment-rotation diagrams of a foundation element (modelled as a volume element) in a dynamic analysis with plaxis 2D or plaxis 3D. I was thinking of introducing a dummy interface or plateen-USTelligent Community 12https://communities.bentley.com/thread/749148?ContentTypeID=1Thu, 12 Jan 2023 16:11:24 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:0b112d16-32ee-4959-8bb4-8d3fc0ae3bfaStefanos Papavasileiou<p>Dear Fausto,</p> <p>Provided I understand the problem you describe, a dummy plate could be used to capture the structural forces of the volume elements. However, please keep in mind the limitations and possibilities when using a dummy plate as an approach. On a different topic, the subject of the dummy plate approach is explained here:&nbsp;&nbsp;<a href="https://communities.bentley.com/products/geotech-analysis/w/wiki/52506/composite-liner-approach-in-plaxis-2d">Composite liner approach in PLAXIS 2D</a>&nbsp;</p> <p>When it comes to time steps of a dynamic calculation, in such case you would need to save all the calculation steps before running the analysis. Then, you would extract the results per step from the tables or via the command line in an efficient way or even with Python scripting in an efficient and automated way.</p> <p>Some interesting articles about this:</p> <ul> <li>&nbsp;<a href="https://communities.bentley.com/products/geotech-analysis/w/wiki/45910/how-to-setup-the-number-of-steps-stored-in-plaxis-input">How to setup the number of steps stored in PLAXIS Input</a>&nbsp;</li> <li>&nbsp;<a href="https://communities.bentley.com/products/geotech-analysis/w/wiki/45553/inspect-intermediate-step-results-in-plaxis-output">Inspect intermediate step results in PLAXIS Output</a>&nbsp;</li> </ul><div style="clear:both;"></div>
