The boundary condition and forces are well defined as well goes for the geometry. Also, the quality of the mesh is perfect with hex8 element multizone. I did a linear analysis and it gave excellent results. Anyway, when I use the Menetry Wiliam model to represent the concrete and UHPC with exponential softening to do non-linear analysis. I used line bodies for reinforcement with bi-linear plasticity The model stops converging and it seems it fails when it reaches it is tensile strength and then stops converging without showing it is softening curve.&nbsp; After trying everything still the model did not get through. My guess of the problem that concrete does not transfer stress with the steel and the reinforcement option is not working for some reason. Could anyone please help me with this issue?? It drove me crazy without being able to fix it at all and I am now considering to use another software because of that issue.&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>Note: I used a small cubic test for plain concrete with menetry wiliam model and it gave the perfect result without having any issue in convergence. So the material should be also well-defined.&nbsp;<\/p>\n","protected":false},"template":"","class_list":["post-365077","topic","type-topic","status-closed","hentry","topic-tag-ansysstructuresolveIssue-1","topic-tag-convergence","topic-tag-learning-hub-1"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 4.9.10 - aioseo.com -->\n\t<meta name=\"description\" content=\"HI,I am trying to model RC for non-linear static analysis.
