    Checking penetrations between parts

    @Dakshitha Since it is the LS-Dyna model and it is related to the solver, I would suggest you contact Dyna support.

    Checking penetrations between parts

    @Dakshitha Could you please share the model file?

    Some questions in Optistruct

    This is a very time taking process. Instead, you can run a ESLM ESLM for Nonlinear Response Optimization.pdf

    Optistruct - composite free size optimization

    HI, I think if you are not providing any laminate thickness bounds, solver uses native thickness to optimize and that is what happened in your case. 0.8mm thickness may not be sufficient to constrain the laminate to a certain displacement and converge to the objective.

    Composite Loading

    Yes, please see the attached image. Thickness and material are missing in the PCOMP card

    Composite Loading

    @LauraT Thickness is not provided on PCOMP for the ply. Please check and try again.

    Error with element energy

    Hi, What type of contact are you using? If it is type7 can you try with Igap= 1/2, change elements to full integration and check the result, please?

    Lattice Optimization Not Solved

    @Aslan I don't see any problem in the .out file. After analysis do you see any .fem file written in the working directory?
  9. Hi @santosh maharana I didn't receive any mail.

    Balance between volume fraction and element density threshold

    HI, Can you check the mass in your model? If mass is not available, please provide density on Material card and try again!!!
  11. HI, This type of mesh is only useful in topology optimization. It does not give meaningful results in a stress analysis.
  12. Hi @baek Please update to 2017.2.4 and check if that helps. If not I may need more information from you.

    material card for Rubber seal

    Hi Teja, There is a tutorial on the gasket in OptiStruct, Please check the same.

    Different Lattice Type But Same Analysis Result

    Hi @Aslan There may be not much change in stiffness, but the lattice structure is different. Did you notice this?

    Hi @Aslan Can you share the .out file, please?
