Hello, Does SimLab provide any function or command to detect symmetry (mirror symmetry) or cyclic symmetry (rotational symmetry) in a geometry or mesh? I could not find anything in the documentation and would appreciate any guidance or recommended workflows. Thank you. SimLab 2025.1
"Hi Support team, I got the error 'This license was already activated using different HostIDs' when activating my Student License. Please help me reset my activation key. Thank you!"
Hello, I need to request the unbinding/reset of the Host ID for my activation key. I have not changed my PC, nor have I replaced or modified any hardware components. I am not sure what happened to cause this license conflict. Please assist me in releasing the Host ID so I can reactivate the software. Thank you!

Description: 수평배치된 연속롤 캘린더링 시스템에서 분체압연 공정시 레코디드 팩토리 기능 Product/Topic Name : EDEM Battery Dry electrode coating system 안녕하세요. LG전자 이유진 책임입니다. EDEM으로 분체 캘린더링 시스템 해석을 진행하고 있습니다. 3-roll 연속롤 배치된 시스템에서 분체를 투입하여 시트화되는 거동을 해석하고 있습니다. 예를 들어 롤 1-2-3으로 배치된 구조에서 롤 1-2를 통과한 분체로된 시트가 롤 2-3으로 투입되어 주행하는 모델을 사용하고 있는데, 해석 시간이 너무 길어서 롤 1-2에…
I have created an LS-DYNA model with a 2D shell mesh for a plate of size 100 mm × 20 mm × 10 mm. The model has excitation nodes selected at the middle of the top edge, and there is a circular hole with a radius of 2 mm at the center of the plate. I would like to study the effect of the hole size on the excitation response…

Hello there, I'm a user of Altair Flux and I wanted to test the SimLab software to see the differences. I'm using the 2026.1 version of Altair SimLab. I have a magnetostatic 3D model of a magnetic source (iron circuit with 2 non meshed coils), I'm using a symetry in all 3 planes. So my idea was to do like in Flux and do a…
