Exporting Free Body loads for multiple load cases change the coordinate system
Hi, The HM2024 model I'm working with has fasteners in different orientations. The analysis systems for the nodes attached to these fasteners have been updated to align with geometry. When exporting the FBD loads tables for all 14 load cases the first load case recognizes the correct CSYS but the remainder cases the loads…

Hypermesh - Bearing Load
Hi, I want to replicate some ANSYS model in HyperMesh. The model contains a hole where a bearing load is applied. In ANSYS software that load is easily applied with a dedicated command. However, I cannot replicate this in HyperMesh. Bearing loads are applied in the half-surface of a cylinder with a sinusoidal distribution…

Issues with exporting control cards
I'm experiencing issues with hypermesh not exporting control cards with models that previously worked without issues. The first time PARAM cards stopped exporting/writing out to the bdf. The PARAM card in the model needed to be delete from the HM model and re-created. HM is now doing the same with GLOBAL_OUTPUT_REQUEST…

How to connect two different existing meshes with CBUSH elements?
Hi guys, I have two panels with different meshes connected by CBUSH elements. I have now received new vectors/locations for CBUSHs. What is the best method to add these new CBUSHs if I don't want to re-mesh anything because I need to keep the previous QUAD element IDs? CBUSHs should connect coincide nodes. Maybe some new…

Hypermesh custom beam section with Sketches issue
Hi everyone, I am attempting to create CBEAM elements (Nastran) to represent some tubes which have an oval shape. The way I am doing it is by line meshing a line with CBEAMs and then assigning a PBEAM property which reference a beam section collector which references a beam section which I defined using a sketch. The…

[OptiStruct] 열전달 및 열변형 해석
OptiStruct 구조 해석 솔버를 이용하여 HyperMesh 인터페이스에서 열전달 해석 후, 그 결과를 이용하여 열변형 해석이 가능합니다. 다음 동영상은 HyperMesh 2024 버전에서 작성되었습니다. Subcase 1에서는 열전달 해석을 수행하며, Subcase 2에서는 열변형 해석을 진행합니다. 해당 데모에서는 10 W/m2의 열유속을 설정하고 RING1의 외부 표면을 0도로 고정하여 열해석을 수행합니다. 이 온도 분포는 열하중으로, RING2에 생성된 강체 요소의 중심은 구속으로 설정되어 열팽창된 결과를 확인할 수 있습니다. 해당 데모는 OS-T 3185:…

uneven stress on pressurized barrel haz
I encountered an issue with a pressurized barrel. To model the welding between two barrels, I applied different material properties to simulate the Heat-Affected Zone (HAZ). The mesh of this component is linked to the other component (with the initial material properties) through nodal equivalence. The geometry has the…
