ボンドモデルの作成について

　ボンドモデルを使用してセフィロシリンダを連続で結合することを考えています．

通常，セフィロシリンダの端と端を結合するようにしてmaterialblockを作成すると思いますが，

そうではなく，端の丸みのある部分を食い込ませて作成することはできるでしょうか．（添付参照）

理由は，セフィロシリンダ間に段差ができるのを防ぐためです．

　可能な場合は，推奨の作成方法（食い込みの程度，作り方手順）と推奨のEDEMバージョンを教えてください．

    Hi,

    It is possible to do this, but I don't believe there is a standard way for doing so. It would be up to you to set a zero force on the particles when they overlap by a certain amount. This might not be easy to determine though as the volume of the overlap will change depending on the angle between the sphero-cylinders.

    You could maybe start by having a contact force of zero if the overlap volume lies between two values? Just a thought.

    There might be rigorous approaches and algorithms for this but I'm not aware of them, so I'd maybe check the literature first.
