Hello,

I am working on drop test simulation of bottle with water inside it. I used TYPE 7 contact for SPH and Bottle. Istf=5 , Iadm= 0 , GAPmin = 0.1, INACTI = 6

But still there is no contact between them. Please correct me.

    Hi,

    I just modified the contact parameters and also the SPH particle parameters.

    Please go through the model.

     

    A similar tutorial/webinar is available which can be accessed at https://altairuniversity.com/conceptual-design-of-a-3-wheeler-motorbike/conceptual-design-of-a-3-wheeler-motorbike-tank-drop-simulation/

    Hi pohan,

    There are some things you should be aware when you set up an /INTER/TYPE7 with SPH.  All of them are concluded in the following images.

    Except from these you can use the recommended values of /INTER/TYPE7 shown in the following image!

    Hello, thank you very much.

    I tested with the default parameters, it worked.

    But with your recommended one, it does not work. I guess in the second picture, they are for the solid solid impact.

    Best

    Yeah, 

    The second picture refers to the solid-solid type 7 recommended values.
