Schematic Link feature - Seeking sample model
I can't get the Schematic Link feature to work. I'm watched the 2 videos that exist showing how to connect a coax harness to a MoM modeled edge trace but the videos do not show the details of the MoM model. Is there a step-by-step for Schematic Link? Or can someone send me a sample of a working model? Thank you very much!

DEM–FEA Coupled Simulation for Granular Packing
Simulating granular packing using DEM and FEA is a powerful way to analyze how granular materials interact with solid structures-especially when both the particle dynamics and the deformability of the structure are important. Coupling DEM and FEA allows for detailed, high-fidelity simulations of granular packing in…

Inspire non-deserialized results and PhysicsAI
Dear community, I have fully parametrized a pressure vessel using Inspire to generate lots of data through DesignExplorer to create a PhysicsAI project. Although, the DoE result files are in a deserialized format, such that each run of the DoE is broken into 6 different "optiResHvtransOut.h3d" files. Is it okay to feed…

Regarding the post-processing issues of EDEM
Hello, the particle size I simulated is relatively small, so I may notbe able to see the particles clearly on the post-processing interface. Therefore, I would like to inquire if there is a way to enlarge and display the particles so that I can better observe their state. The version I am using is EDEM2024 Thank you!

Python hwx library extrude-substract problem (Inspire 2025)
In the Python hwx library, the “extrude” function is explained as in the image, but “parts” does not work correctly. For example, I wanted to do a Substract operation with the following line of code. In the code, I specified “parts=substractPart” in the function. Although Part(1) appears in the “Merge with” section of the…

非線形静解析で、指定した拘束反力に到達したら計算を終了する例題
はじめに 非線形静解析では、少しでも収束をよくするために、荷重で変形させるのではなく、強制変位で変形させることが良くあります。 とはいえ、強制変位でも座屈が起きれば収束できませんので、ある程度反力が出たところで、計算を打ち切りたい、という場合もあると思います。 OptiStruct には SENSOR というカードがあり、このコントロールができます。 本記事では、実際に例題を一つ示します。 SENSOR カードの説明 バルクセクションで定義した SENSOR カードを、サブケースセクションで参照するという仕組みになります。 まずは、バルクセクションの SENSOR カードの説明を、拘束反力到達で打ち切る場合について、説明します。…
