SPHのSmoothing lengthを変えたものを2つ用意し、双方向の接触をさせた時は接触条件を設定すべきですか？すべきであるならばどのような設定をするべきか教えていただけるとありがたいです。（SPHで砂を模擬しています。）

    Hi,

    The smoothing length should be calculated according to the sph network refinement. If your sph network is well distributed, then you can take the smoothing length as 1.5 times the distance between sph particules.

     

    I am not sure I understand exactly what you mean by bidirectional contact...

     

    Are you talking about contact between 2 sph parts? or between 1 sph part and a standard lagrangian part?

     

    Regards,

    Mathis
