    Stress concentration problem in FEA

    Hi, Thanks for the explanation, I realised I was confusing terms which are different (stress concentration/singularity). I could not get convergence, so I was talking about a singularity caused by a boundary condition. I would have to get a more realistic condition, for example by using...

    Stress concentration problem in FEA

    First of all, I´m very grateful for your help. Yes, I realised the problem is bigger than I thoght. Firstly, the objective wasn't solving this subject, in fact that part of the piece wasn't going to be analyzed by FE since tests were performed. However, I'd like to make sure I can't model it...

    Splines in ANSYS Workbench

    Hi, I should have explained you before why I wanted to use only ANSYS. Sorry about it. The reason was because working with both programs in the process of optimization would do it very slow since it run the analysis for different geometric parameter combinations (it would open the CAD program...

    Stress concentration problem in FEA

    Hi all, I have a problem of stress concentration or singularity. Stress is increased as mesh size is decreased. There is no convergence, so results are unreal. I have learned a lot about this problem in other threads of the forum. But in this case I am not interested in knowing if the peak...

    Splines in ANSYS Workbench

    Yes, I knew that, but I wanted to use only ANSYS. I suppose that is not possible. Anyway, thank you for your attention cbrn. Regards

    Splines in ANSYS Workbench

    Hi all! I'm working with ANSYS Workbench v11 and I'd like to know if there's a limitation in the use of splines in DesignModeler. That's because if you change a parameter of a spline (like the position of a point) and then change it again to the initial value, sometimes you don't get the same...
