Simlab-EDEM Coupling-vacuum machine
I'm using Simlab to model a vacuum machine, and in coupling with EDEM the particles should be moved upwards once it touches certain part of tube. How do i define the face to give particle velocity in Simlab 2025 Optistruct solver? Thanks Qin

Reading coupled geometry pose in an EDEM Particle Body Force UDL (MotionSolve co-sim)
Description: 현재 EDEM–MotionSolve Co-simulation을 통해 CFD Field Data를 EDEM에 적용하는 시뮬레이션을 진행하고 있습니다. 형상(Geometry)의 Motion에 따라 Field Data의 적용 위치도 함께 갱신되도록 구현하고자 합니다. 즉, 형상이 이동·회전할 때 그 움직임을 Field Data가 따라가게 하여, Particle Body Force UDL에서 필드 기반 힘을 형상 기준으로 조회하려고 합니다. 해당 형상은 시뮬레이션 중 이동하며 pitch 각도가 변합니다. 이를 위해 EDEM API의 Geometry 관련…
