Consumer Electronics Drop Testing. Part 4: HyperStudy Setup
Overview A drop test scenario has been devised for consumer electronics, focusing on the phone's housing and display, which are depicted as flexible bodies. To accurately represent the internal components, appropriate mass and inertia values are assigned. By utilizing Euler angle rotations (Yaw-Pitch-Roll), users can…
Steady-State Detector for Early Stop in Twin Activate
Overview This is a Twin Activate block which stops the simulation when the response of a system stays within an allowed range from the desired system response. It can be used with any system in which the desired response and actual response can be compared. Usage This is how the block should be implemented in a Twin…

接触計算のタイムステップを効率化する方法
Overview Altairのマルチボディ解析ソフトMotionSolve/MotionViewには接触計算時に、接触計算の精度を上げるため、接触を検知したのち、タイムステップを小さくする機能があります。ただし、一度接触を検出し、タイムステップが小さくなると、計算終了までタイムステップは小さいままです。本記事では、接触検出の後、再度接触が発生しなくなったときに、タイムステップを元に戻す方法を紹介します。 Contactにて、Find precise contact event（デフォルト=0.01）とChange simulation max step…
