Hi everyone! I am running nonlinear analysis of channel section beam in Ansys Workbench, fixed at the one end and simply supported on the other. The problem is that the curve has a long flat part (please see picture) - Ansys couldn't aciheve convergence between two substeps. I have tried to...

Hi! I want to model I section with 0 thickness so as to get surface beam with assigned thickness and shell mesh. But I am facing a problem. I cannot make I section because I get errors like: Operation would result in illegal T surface bodies. Firstly, I have created the web by extruding a line...

Hi! Can somebody explain in general steps how to perform thermail beam buckling in Ansys? I have simple beam fixed on both ends and want to know what is critical temperature that cause beam to buckle. Thank you in advance.

Hi! Does anyone know how to perform thermal buckling in FEMAP? I have clamped beam with const. temperature load applied in all nodes/elements. When i ran buckling analysis I cannot get translation of the beam due to different temperature applied. the beam buckles but value of the translation is...

Thank you all for replies, you really made my day! I was reading a lot about rbe2 and rbe3, but it was hard to understand it percisely. Leo16, i tried you recommendation and it went really good (i have some results to benchmark). i think that i get it now. Thank you for your help! Sandra

Hi! I am having a problem with buckling analysis. I have a box beam made of plane elements clamped on both sides, but i need to apply force at one end in the middle of the cross section which means that i have to use a spider node. but, i am not sure how should i define element at the spider...
