I&#8217;ve chosen to use tetrahedral meshes and a Yeoh model, as this resembles my model, which is not a simple beam. On this 1st simulation, there&#8217;s the command <strong>inistate,write<\/strong> which allows me to save the stress generated after the result of my simulation (can you please confirm?).&nbsp;&lt;\/p&gt;&lt;p&gt;2) On the 2nd simulation, run with the <strong>main_prestress.mac<\/strong> code, I removed the loading (gravity) and imposed the prestressing obtained in the 1st simulation with the <strong>inistate,read<\/strong> command. The simulation does not converge. I&#8217;d like to obtain the same result as in the 1st simulation (as shown in the photo of the results). It probably doesn&#8217;t converge because the inistate command applies too high a stress to the first substep. Do you think it&#8217;s possible to make this simulation converge? And if it does converge, do you think I&#8217;ll get exactly the same result as the 1st simulation (because that&#8217;s what I&#8217;m looking for).&lt;\/p&gt;&lt;p&gt;3)) For the 3rd simulation, run with the <strong>code main_blocked.mac<\/strong>, I tried to do your method with the command <strong>DDELE,all,all,,,FORCE<\/strong>, but it doesn&#8217;t converge either.&lt;\/p&gt;&lt;p&gt;Any help would be appreciated. Thanks again for your answers.
