NOTE: A solid, in-depth understanding of MotionView for vehicle modeling and OptiStruct for structural analysis is essential to successfully implement this type of MotionSolve–OptiStruct co-simulation workflow. *Refer to the attached folder, containing detailed process of the MS-OS Cosim workflow along with all the model…
はじめに /PROP/KJOINT2 を利用した球ジョイントの例題です。 球ジョイントは、リンク間の距離は変わらない (*1) けど、回転は自由に行えるジョイントです。 剛体リンク、などと呼ばれることもあるかと思います。 *1) 固いばねなので、実際には少し変形します。 例題 ダウンロード: https://us.v-cdn.net/6038102/uploads/GDKM6MAAZQSI/model01.7z このようなシンプルな例題です。…
INTRODUCTION Iron roughnecks are hydraulic devices widely used in the oil and gas industry for the automation of critical operations on oil rigs. Historically, these systems were introduced to improve the safety of oil rig workers while connecting and disconnecting drill pipes. Without such systems, these operations would…
This is the query csv file export tcl script. *hyperview_qurey.tcl When you execute the tcl file, a csv file is created in the pwd path. (You need to select the model file and result file in the GUI). 1. you can specify the file in advance through variableization. The first file is the model file, the second file is the…
The FiberBuilder.xlsx spreadsheet can be used in order to procedurally generate fibers with various shapes in Altair EDEM. The position and orientation of all particles composing the fiber are automatically calculated and can be directly imported as a meta-particle within the software. A sample simulation including fibers…
해당 스크립트는 사용자가 지정한 경로 및 파일 확장자에 대해 확인하여 OptiStruct를 배치 모드로 실행하는 스크립트입니다. 다수의 OptiStruct input 파일을 순차적으로 실행시키고자 할 때 사용할 수 있습니다. 사용 방법: py 파일을 텍스트 편집기로 열어 아래의 내용을 수정하고 저장 osPath : OptiStruct가 설치된 경로 지정 path : 해석 인풋 파일이 위치한 최상위 폴더 경로 지정 ncpu : 해석에 사용할 CPU 수량 입력 cmd 창 열기 py 파일 위치로 이동 python *.py 명령어를 입력하여 py 파일 실행 참고 사항:…
始めに 本記事では、節点対エッジ（要素辺）、エッジ対エッジ接触が、/INTER/TYPE{7,11,19,25} でそれぞれどのような挙動になるのか、例題を通じて理解していきます。 なお、長くなるので、本記事では、/INTER カードについての細かい説明はしません。 例題の説明 ダウンロード: https://us.v-cdn.net/6038102/uploads/0XK57TUZ8UEF/models.7z このように、３個のパターンで、青のシェル要素に緑のシェル要素をぶつけてみます。 節点対要素面接触 /INTER/TYPE7 節点体要素面接触の /INTER/TYPE7 です。…
Overview: Here is the file used in the video on editing geometry and creating a hexa mesh. https://us.v-cdn.net/6038102/uploads/KEPABX3ZWHTE/impeller-hexmesh.zip Release Version: 2025
始めに /INTER/TYPE25 接触は、貫入量に関わらず、接触剛性 (仮想ばねのばね定数) が常に一定です。 https://help.altair.com/hwsolvers/ja_jp/rad/topics/solvers/rad/inter_type25_starter_r.htm 一般的には、Radioss に接触剛性の決定を任せます。…
Foreword I’m excited to share the innovative work of my colleagues, Nadine Kåmark and Christoph Mäurer, who have tackled the complex challenge of automotive radar integration under severe vibrations. Their research demonstrates how Altair’s HyperWorks suite can model and analyze the impact of dynamic conditions, such as…
