[SimLab] OptiStruct 결과에서 Rigid 요소 인접한 부분을 제외한 값 확인 방법
Rigid 요소로 생성한 영역 주변에서 응력에 튀는 경우에는 보통 Rigid 요소와 연결된 1~2 layer를 제외하고 구조 해석 결과를 확인하기도 합니다. SimLab 후처리에서 해당 작업을 직접 지원하지 않기 때문에, 해석을 수행하기 전 제외하고자 하는 영역을 set으로 미리 생성해두어야 합니다. 만약 이미 생성된 해석 결과에서 해당 작업을 수행하고자 한다면 HyperView를 이용해주시기 바랍니다. 해당 동영상은 이 과정에 대한 내용으로, SimLab 2025.1과 OptiStruct 2025.1 기준으로 작성되었습니다.…

How export non-spherical particles in EDEM?
Hi, I want to create a non-spherical bed of particles and use the results as the geometry of my CFD simulation. When I wanted to export my particles via export as stl, the software gave me error that exporting cannot be done for this particle shape. How can I export non-spherical particle shapes as stl file? Thanks.

Accessing Statistically-Based Design-Allowable Properties Using MMPDS Data in AMDC
In finite element analysis (FEA), the accuracy of your simulation is only as good as the input data - particularly the material properties. In safety-critical applications such as aerospace, defense, and automotive, using nominal or average material properties is not enough. These values don’t account for natural…

Particles disappear
Hi, I am doing a simulation of a ramp that vibrates and has particles. The issue I am having is that when the ramp starts to vibrate, after 0.05s the particles disappear. I have tried reducing the Rayleigh Timestep/ Percentage, but this keeps happening. Is there any other reason why particles might be disappearing and how…

Magnetic-Transient solve stops with “ill-connected elements” although mesh check is clean
Hi everyone, I’m modelling an axial-flux machine (AFM) in SimLab 2025. My CAD is imported as a STEP file and meshed inside SimLab. I have already run three transient magnetic simulations successfully; the only difference between them was the magnet arrangement on the rotor. After applying a new magnet pattern the solve now…
