Hi, I'm modeling a stiffened sphere subjected to external pressure and to expansion due to high temperature. I performed a geometric non linear simulation considering only the external pressure and now I'd like to evaluate the effect of the high temperature. How can I include it in the analysis? I can't find nothing similar to the TEMP entry of the linear static Thanks, Enrico
Hello I want to analyse the post buckling behaviour of an arched plate (SHELL Elements) with GNA (Geometric nonlinear analysis, implicit). The model is attached. In another forum (RADIOSS) a similar case was presented, with an pdf file attached, discribing a similar problem : I am not able to reproduce the results (should be look like this: I tried different parameters for shell thickness, force size, starting load increment size and solver options (Arc, RIKS,...). Sometimes I get nothing at all, sometimes only results up to point A (s. picture above). How can I get post buckling results? Thank you PlateTest.fem
