    Using Simsolid

    Got a question about the best way to use a SIMSOLID capability or if SIMSOLID can do a specific function or task? Post it here.

    Catching An Error

    So what is the action you need the user to take when the analysis fail?

    GUI for HyperMesh Script

    And is there a way to suppress this command to change the framework? (Because it takes the user to another "page" when this command is called) Or just embed it within the Collector widget?

    FLD and rolling direction

    Hi all, 1- As sheet metal resistance to thinning is not the same in different directions (which is the subject of Lankford coefficients), how can we define FLD curve without considering rolling direction? 2- In Radioss one-step forming simulation in which we define r0, r45 and r90 during material definition, is there a pre-defined sheet rolling direction? Is it X axis or what? Thanks in advance.

    Topographieoptimization - Beadfrac

    The idea of first performing optimization at the lower and upper bound of beadfrac parameter is to gain an understanding of the range of performance metrics you are trying to improve. In the following step (minimize beadfrac as objective) use the relevant performance metrics from upper/lower beadfrac optimization runs as constraints to formulate a reasonable/feasible optimization problem. The optimization to minimize beadfrac can be run with initial beadfrac=0, but you can also run with initial beadfrac at lower and upper bounds (-1 and 1) to evaluate if the design converged to local or global optimum.

    Add button script

    Hello all I'm have a question How I can add a button to tab area\menu with a tcl\tk script? P.S. "View ->Toolbars" and then i don't have "Options".
  12. Hi all, I wanted to know if actual springback after forming depends on sheet rolling direction. As anisotropy coefficients (r0, r45 and r90) affect thickness reduction, I think they must be important in springback analysis but during routine process (as defined in related tutorial) which is performing springback analysis following an incremental forming simulation, they are ignored at all. Am I wrong? Thanks in advance.
  13. Hi, I used the same fem file which I used for the Optistruct 14 run (see atached files from my first post), I only used the Optistruct 2017 solver (since I want to do the same analysis ) .... Is it wrong doing so ? Regards, Szilard
  14. can you share the .fem file setup using 2017 version.

    Fatigue Analysis

    Please download free eBook on Fatigue analysis using Optistruct. https://altairuniversity.com/free-ebook-learning-fatigue-analysis-with-optistruct/
  18. Hi Rahoul, here are the results when I run the same input files under Optistruct 2017. My problem is that the same pretension lodcase (enforced displacements in a local csys) produces different results whether there is a follower loadcase or not..... Regards, Szilard
  19. Hi Ayil Have a check at the e-book, practical aspects of finite element analysis. https://altairuniversity.com/free-ebooks-2/free-ebook-practical-aspects-of-finite-element-simulation-a-study-guide/ Check this document too https://altairuniversity.com/learning-library/hypermesh-element-quality-check-and-mesh-styles/ Thanks
  20. Dear Rahul Thank you for your reply. I have tried using fixlen some days ago and it worked! Thank you very much!

    Geometry is sudden transparent

    Hi Alex Nguyen Have a look at the different model visualization options in HM. You can check the transparency option also. Thanks
  23. can you share the files of 2017 version.

    Topographieoptimization - Beadfrac

    First, define compliance response Second, define compliance response constraint (dconstraint panel). I think you should give a specific lower bound (the minimal compliance value).
  25. Hi, thanks for your answer, I tried to solve with Optistruct 2017, unfortunately occours the same problem....We don't use Optistruct 2018 at the moment. Regards, Szilard
