how to set constrains conditions for welding plastic tank in simlab
I wonder if someone has the experience to do the simulations for plastic or maybe metalic tanks like expansion tanks that have two seperated parts which have been welded together. I have been doing like this: importing two parts and then make them booleaned and then contact I make them tied. So this way the two parts are…

How to handle intersection issue in simlab as well as Hypermesh ?
Hi Good Day, In SimLab, we typically use the Element Intersection tool to detect intersecting elements, remove them, and then rebuild the mesh either manually or using the autofill option. However, I’m looking for a way to address these intersection issues directly at the CAD/geometry level. For CFD meshing, Boolean…

what are the difference between coupled solution and the structural solution with mapped temperature
I noticed that the results from the same models with coupled solution and the structural solution with mapped temperature and pressure are different(from pdf of heat transfer analysis training), is it because that within the coupled solution, the displacements of the model will be sent to flow solver to recalculate the…

Inject current in motor SIMLAB
Hi, I am trying to inject a current in the motor windings but I can not select the internal face since I get the error: "The selected body does not have any internal face". I even tried to generate the geometry through an assembly coupling to identical parts to form the windings, but I still get the same error. PS: I am…

[SimLab] OptiStruct 결과에서 Rigid 요소 인접한 부분을 제외한 값 확인
Rigid 요소로 생성한 영역 주변에서 응력에 튀는 경우에는 보통 Rigid 요소와 연결된 1~2 layer를 제외하고 구조 해석 결과를 확인하기도 합니다. 후처리 시 해당 부분을 숨기고 결과를 보는 방법은 2가지가 있습니다. 해석을 수행하기 전 set으로 생성한 뒤, 후처리 시 해당 set을 숨기기 해석이 완료된 상태에서 숨기고자 하는 요소를 선택하여 body를 구분하고 숨기기 해당 동영상은 SimLab 2025.1과 OptiStruct 2025.1 기준으로 작성되었으며, 후처리 시 선택한 요소를 숨기는 작업은 2025.1 버전부터 지원되는 기능입니다. 구버전을 사용하는…
