How can I convert implicit part to triangle mesh with python code using hwx library? (Inspire 2025)
Hi there, I created a body-centered cubic strut lattice using a simple cube. I want to convert this lattice structure to triangle mesh with python code. But I want to do this with the new feature “Create sharp edges and specift mesh size” option and “Average mesh size” value of 0.2 mm in Inspire 2025. I could not find the…

Nut Mixing and Packaging System Simulation in EDEM - Material Dosing
A significant proportion of food produced globally is never consumed, with around 14% lost between production and retail [1]. While food loss can occur at various stages of the supply chain, improving bulk material handling in food processing—through virtual testing and system optimization—can help reduce losses and…

Scripting ADF's To Simulate Steering Events In MotionView
Overview: The vehicle library within Motionview contains a vast amount of verification tests, however there will come a time where a unique event needs to be simulated. In order to do this, we can generate our own Altair Driver Files (ADF) to simulate the task! This post will go over two different types of steering events…

Why it is not showing stress value for the nodes which shares it with multiple components ?
When I try to measure stress value(stress plot) through Measure —> Nodal Contour for the nodes after isolating any particular component which shares nodes with some other components will not show stress value instead it will show NA. If you try the same scenario in the old version like 2019,2021 or 2022 it will work…

제 23편 Boundary Condition
오늘은 Boundary Condition(경계조건)이 무엇인지 살펴보도록 하겠습니다. 경계조건이 무엇인지 2가지 경우를 통해 비교해 보겠습니다. 1. Simply supported(단순 지지) 2. Fix-Fix(양단고정 지지) 이 두가지 경우를 단순화 시켜보면 아래의 두가지 경우로 나뉩니다. Simply 과 Fix-Fix의 경계조건의 차이점은 단지 하나의 자유도(6) 입니다. 단순지지의 경우 양 끝단에 1,2,3,4,5 를 구속. 양단고정 지지는 양 끝단에 1,2,3,4,5,6을 모두 구속. [참고] 1: X축 병진방향 자유도 2: Y축 병진방향 자유도 3: Z축 병진방향…

제 22편 Linear Elastic Material Information
오늘은 HyperMesh 에서 궁금했던 Material을 파헤쳐 보도록 하겠습니다. 일반적으로 같은 Force(혹은 같은 Stress)에도 Material 이 다르면, 다른 변형률을 얻습니다. 많은 Material들의 간단한 인장시험 결과를 보면 작은 변위에서는 Stress와 Strain 사이에 선형적인 관계가 존재합니다. 당긴 만큼 비례해서 늘어난다는 것이죠. 아래의 σ=Eε가 바로 Hooke’s Law 입니다. (등방성 재료의 경우, 아래 내용 참고) 이 방정식은 Linear Elastic 거동에서 적용이 됩니다. [ E of Material in HyperMesh ]…

제 21편 Element Quality
1. Element Quality (요소의 품질) 요소를 생성 하고 난 다음 꼭 해주어야 하는 과정이 있습니다. 바로 품질을 체크하는 것인데요! 요소의 품질은 Solution에서 해의 정확도와 관련이 있습니다. 아래를 보시면 요소의 일반적인 기준을 나타낸 그림입니다. Best가 가장 이상 적인 요소입니다. 2D라면 정삼각형, 정사각형, 3D 요소라면, 정사면체, 정육면체가 되겠죠? 우측으로 갈수록 요소의 품질이 낮아지는데요, 복잡한 모델일 수록 Best 요소로 생성하기는 어렵겠죠. 품질은 사용자가 원하는 해석에 맞게 기준을 정해서 판단하시면 됩니다! 1.1 품질 기준 –…

이번 시간에는 Hexa Meshing에 대해서 살펴보도록 하겠습니다. [Manual Hexa Meshing] 복잡한 Part에 Hexa Meshing을 생성하는 방법은, Surface에 Shell 요소들을 생성 한 뒤, 3D Meshing 기능을 이용해서 Hexa 요소로 바꿔주는 것입니다.
Extrude, Revolve, Sweep, Linear Solid 같은 기능을 이용해서 말이죠. Hex Meshing을 완료한 후에는(Free face check) 노드가 공유 되어있는지 확인 하는 것이 중요합니다. 1) Extrude/Revolve *Topology >…

제 19편 3D Meshing (Tetra) -1-
이번 시간에는 부피를 가진 3D 요소에 대해서 살펴보도록 하겠습니다. 1. 요소의 타입 Solid (사용자가 두께 등의 추가 정보를 입력하지 않아도 됩니다.) 2. 요소의 형태 Tetra, Penta, Hexa, Pyramid ( 윗줄은 1차 요소, 아랫줄은 2차 요소입니다.) 3. 주로 쓰이는 곳? Gear Box, Engine Block, Crank Shaft 등에 사용됩니다. 4. Solid 요소의 자유도는 병진방향만 존재합니다. 1D요소 와 2D 요소는 6개의 자유도를 가지고 있습니다. 자유도를 쉽게 표현해보면, 긴 자를 압축하거나, 얇은 종이에 압축력을 가해주면…
