aeroelasticity of a Formula 1 front wing
Hi everyone, I’d like to do a not-too-complicated aeroelasticity study of a Formula 1 wing I found online with a linear static FEM. This is the procedure I’d like to follow, but I’m not sure how to handle one step: Perform a CFD analysis of the wing Extract the pressure field around the wing Import the CAD into HyperMesh…

How to Reflect the component without creating nodes in New GUI HM like in old version?
Hi, In the older version, we could select points directly to define the base node. How can we do this in the new HyperMesh GUI? I noticed that if there are no existing nodes in the CAD model, I need to manually create a base node to perform the Reflect operation. Thanks, Mugundhan.…

Quality Check Criteria
Just noticed something that is troubling me. When looking at Element Quality in 2025 version of HyperMesh/Optistruct, in the Criteria display, even though I have set the criteria in the Criteria Editor, the Iso plots in "Criteria" don't use the same Fail criteria. For example, in the image below, the aspect ratio Fail is…

Extracting Stresses in Elements
Hello, I've been running an optimization based on non-linear analysis (LGDISP). The results I need are the stress resolved in the Elemental System: However, when using HyperStudy, the software extracts data only in the Analysis System, and in the data source configuration there isn’t an option to extract results in the…

HyperMesh-Optistruct를 이용한 압입 해석 튜토리얼
압입해석 Press-Fit 해석은 일반적으로 샤프트를 하우징에 밀어넣는 과정에서 발생하는 응력 및 변형률을 확인하는 Pushing 해석과 샤프트와 하우징간 간섭으로 발생한 잔류 응력을 해석하는 Interference-Fit 해석으로 구분됩니다. 이번 글에서는 샤프트와 하우징간 간섭에 의해 발생하는 Interference 해석을 진행해 보도록 하겠습니다. Interference 해석은 일반적으로 하우징과 샤프트가 체결된 상태에서 구조물간 간섭으로 인해 발생하는 응력을 계산할 때 수행하게 되며, 아래 그림과 같이 모델이 겹쳐진 상태로 모델을 구성합니다. 하우징과 샤프트가 이미…

Contour plot of strains
I feel very embarrassed to ask since this must be an incredibly basic thing, but how do I get a contour plot of strain from HyperMesh (using results of an Optistruct model)? I can get contour plots of stress easily enough, but strain just seems to not be an option. I have tried activating the Strain Global_output_request…

Hypermesh heat transfer contact conductance issue
Hi, I’m performing a steady-state heat transfer analysis in HyperMesh 2024.1. Currently, I observe a very small temperature gradient in my results, and I suspect it might be a visualization artifact from the software. My assumption is that even if shell structures are perfectly joined, a contact definition is still…

Inquiry About Pushrod Suspension and Anti-Roll Bar Models in FSAE_BAJA Library
Hi, I hope you’re doing well. I wanted to ask if there are any existing models in the FSAE_BAJA library that can be adapted to simulate a pushrod suspension system with either a U-shaped anti-roll bar or a dual-blade (Z-bar) anti-roll bar, as I haven’t been able to locate one. If no such model exists, would it be possible…

Modal Analysis of plate with foam material attached to it
I am performing the modal analysis of plate with foam strips attached to it . The thickness of strip is 1 mm in free condition while 0.6 mm in compressed condition. I have to observe the first 10 natural frequency of this setup. How can I model this behavior of foam being compressed by 0.4 mm in modal analysis

The problem with splitting geometry
I have a very large model with a lot of solid, which was imported into Hypermesh in IGES format. After the import, the model consisted of a large number of solid objects that were not connected to each other. I do the manual work of suppressing and combining solid. But often, when cutting solid objects, the points of…

Problem exporting mesh from HyperMesh to Forge NXT
Hello everyone, I imported a STEP file of a thin sheet metal part into HyperMesh to create a mesh and then export it to Forge NXT (Transvalor). However, I’m having trouble finding the correct export format for the mesh. Forge NXT requires either a .unv or .nas file, but I can’t find these formats in HyperMesh’s export…

Contact - STATIC LINEAR ANALYSIS
Hi guys, I am trying to set contact for linear static analysis. I am working in HyperMesh 23.1. From previous colleagues I found a model made in HyperMesh 14.0. This model is working OK after analysis start in NASTRAN. Based on this model I tried to make the same one - imported old model to hypermesh 23 and created the…

What is 1D Element Force for CBEAMs in non-linear static analysis
Hello, I am having trouble understanding what 1D Element Force in HyperView is providing for cbeams. In particular for a L section cbeam element without offsets in a non-linear static analysis when load is not applied at the centroid. I would have expected the 1D Element Force to be equal to the FBD of the same element but…
