I am investigating a coincident node between the top and bottom plates. However i am not getting the expected hyteresis loop after running a transient analysis with the details shown below. can you kindly help with this. screens<img decoding=\"async\" title=\"Model and contact details between the top and bottom plate\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/02\/16-02-2024-1708122849-contact details.png\" alt=\"\">hots attached are <img decoding=\"async\" title=\"graph of force against relative displacement between top and bottom coincident node\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/02\/16-02-2024-1708122927-hysteresis loop.png\" alt=\"\"><\/p>\n<p>the pretension and harmonic load <img decoding=\"async\" title=\"pretension and harmonic load applied\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/02\/16-02-2024-1708123171-pretension and harmonic load.png\" alt=\"\">force applied are also shown.<\/p>\n<p>The analysis settings is as follows<\/p>\n<p><img decoding=\"async\" title=\"bolt pretension applied\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/02\/16-02-2024-1708123406-bolt pretension.png\" alt=\"\"><\/p>\n<p>j<img decoding=\"async\" title=\"Transient analysis setting\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/02\/16-02-2024-1708123552-transient analysis settings.png\" alt=\"\">i I have not been able to figure out why i cannot get the expected hysteresis loop so as to be able to analyse the energy loss.
