    I don't think this is error.If it is error, then it would have listed out with some message in the status bar.

     

    Note: Its always recommended to use the latest version(For 2017version the latest patch was 2017.3 and for current version 2019 the latest patch is 2019.1)

     

    Hi,@Rahul R,

     

    I have upgraded the software version from 2017.2 to 2019.1, but the same problem still occurs. I am very confused and do not know what to do.

     

    There were no problems in the first 12 calculations, and then an error was reported. After I opened the model file that was

     

    reported, I found that the angle of the composite layer changed to 50 and the thickness of the layer changed to 60.12. here is.study file。

    Study_1.hstudy

     

    I'm in a hurry and don't know what to do。

    You could refer to HyperStudy quick start example where we have ply stack model, which covers ply thickness and stacking sequence as input variable.

     

     

    Hi ,@Rahul R  

     

    The solver in the above tutorial is Optistruct, can this optimization method be applied to Ls-Dyna?

     

    In addition, there are only 4 types of composite layups, and the final optimal layup order can only be derived from the four layup sequences set previously.

     

    The composite layer I want to use is too much to be listed in the tutorial. Is it possible to optimize automaticly the layup thickness and layup order like Optistruct?

    How to solve this problem,  is it related to the software version?

     

    Where can I download the latest version of hyperworks?

    I see you are using HyperStudy 2017.1 and would suggest you refer attached document for ARSM based optimization algorithm for termination of optimization.

    ARSM 2017.2.pdf 340.81 kB · 0 downloads

     

    Thank you,

     

    Is it possible to send the .tpl file to you, and check if it is wrong, but my .tpl file is too large to upload, is there any other way to send it to you?

     

    Why can't I find the MAXFAIL option?

    Which optimization method you are using?Also try by setting the ignore failed evaluation.

     

    @Rahul Raj Thank you very much

     

    The optimization algorithm I used is ARSM.and set the ignore failed evaluation. like figure 1

     

    But when the invalid iteration is more than 10 times,like figure 2. the optimization is automatically terminated. My .tpl file is too large to upload, and I don't know how to solve this urgent problem.

    HyperStudy is Solver neutral.Optimization can be performed using the analysis solver directly, or by using a fitting function.For Linking Input variable , you could refer to below HyperStudy online tutorial.

    HS-1060.

     

    Thank you,@ Rahul R

     

    HS-1060 is a variable connection between different models. What I want to achieve is how to link two variables in the same model.

  8. in my optimization model, the intrusion amount and intrusion speed of the B-pillar are used as constraints.

     

    The intrusion amount is measured by measuring the amount of intrusion of the B-pillar by reading the deformation amount of the spring element by providing a spring element between the left and right B-pillars. But how to output the deformation of the spring element in Hyperstudy-Dyna,


  9. Hi,The optimization objective in the Hs-1560 tutorial is the total quality. I don't know how to set the total mass of some of these parts to the optimization objective, not the total mass of all parts.

     

    Can Hyperstudy-dyna achieve this goal?

     

    In order to achieve the minimum weight of the B-pillar under the collision condition of the vehicle, how to set the optimization objective in Hyperstudy,

    Is this the first Dyna HyperStudy setup for you?Which version of HyperStudy you are running?Or Other cases of Dyna HyperStudy cases are running fine.

     

    If this is the first case which you are trying ,then i guess it could be an issue related to solver script.If possible please share.hstx file.

     

    Yes,Its the first Dyna Hyperstudy,the version is 2017.2. I can't find .hstx file,where is it ?

     

    can you provide some relevant tutorials or examples? thank you
