Create multiple coordinate system with CBUSH
Hi all I need to create CBUSH elements connecting surfaces with multiple curvatures. In general, I use to create these CBUSH automatically using connectors tool but, to have the CBUSH axis aligned to a local coordinate system normal to the curvature, I still need to create the CSys manually. Is there any simpler and faster…

SimLab not opening/crashing on startup
Hello, I've just reinstalled SimLab 2024.1. When I try to open it, the popup gets to "Loading SimLab" before disappearing. I had no issues before uninstalling, the only difference is that I included the SimLab2024.1_Additionals folder in the installation. I've tried restarting my PC, changing power modes, VPN/antivirus…

Where does a DOE pick up the data from when generating reports ?
Hello, I've created a DOE, ran it on the local server but I've ran into an issue when generating the reports. I've used Design Explorer to generate the DOE, exported the files and ran them on the server and now I'm using HyperStudy to generate the report from this DOE. I've generated a report on a previous study that I've…

Problem with Second Phase of composite optimization (Sizing)
Good afternoon, I’d like to share my problem: Starting with a laminate [0/45/-45/90/90/45/-45/0] with 1.5 mm thickness per layer, I carried out a free-size optimization to reduce the mass while imposing a Tsai-Hill constraint with an upper bound of 0.1. This configuration for the free-size phase has been the most effective…

모터 블레이드 해석 관련
안녕하세요. 이전 Q&A를 통해 모터 정적해석을 하는 중이며 응력 및 변형량 등의 결과값을 확인하는 중에 궁금증이 생겼습니다. 현재 Rforce를 이용하여 rpm을 input값으로 설정한 후 모터의 변형량을 보고 있습니다. 여기서 궁금한 점은 system을 설정 할 때 COM(Center of Mass)혹은 COG(Center of Gravity)를 고려하여 system 좌표를 해당 노드로 옮긴 후 해석을 해야하는지, 아니면 축과 COM,G와 상관없이 돌려도 되는지 궁금합니다. 또한 COM 계산은 어느곳에서 찾아야하는지 현재 메뉴얼을 보고도 찾지 못하고 있습니다.(COG는…

Calculating Static Rollover Threshold Using Automotive Tilt Table Event and MotionSolve
Preface: The automotive Static Rollover Threshold (SRT) refers to the maximum tilt angle at which a vehicle is likely to tip/roll over during a static situation. The SRT can be used to predict the vehicle lateral acceleration in which rollover may occur. Vehicles with a low Static Rollover Threshold (SRT) are at a greater…

[PSIM 2022.2]Need assistance with IGBT and Diode Temperature Settings in PSIM 2022.2
Hello, I am working on a model that utilizes an IGBT component where the IGBT's temperature is set at 125 °C, while the antiparallel diode's temperature is set at 75 °C . In the version I am currently using (PSIM 2022.2), I believe there is no equivalent component that allows me to impose separate temperatures for the IGBT…
