Overview The 'Frictional Heat' API introduces frictional heat effects into your DEM particles within your EDEM simulation. This API calculates the heat generated due to friction and allocates equal heat flux to the interacting elements. An example is also attached that shows the usage of the API. Prerequisite: EDEM 2025.1…
始めに 非線形過渡解析の、一般的な出力間隔は SUBCASE 内で指定する NLOUT で決めるので、どの出力も同じ間隔で出てきます。 しかし、DISPLACEMENT などの出力要求カードは直接 NLOUT を指定することができ、また、出力先のファイルも H3D や OPTI 等選べるため、全体のアニメーションは控えめなコマ数で、特定節点や要素の状態量は細かく、ということができます。 Radioss ユーザーからすると、アニメーションファイル (Aファイル, .h3d) と履歴ファイル (T01) のような関係となるような、出力ができるということになります。…
Overview The 'Buoyancy' API introduces buoyancy forces to the DEM particles without using a coupling with a CFD solver. There is also an example attached that shows the usage of the API. Prerequisite: EDEM 2025.0 or above Usage/Installation Instructions: Extract the zip file attached. Copy the 'Buoyancy.dll' from the…
はじめに 題名の通りなのですが、面対称モデルの対称面に RBE3 を付けても、フルモデルから期待するような振る舞いにならないですし、もちろん、フルモデルと結果も違います。 例題を通じて、そのことを理解していきます。 RBE3 に関する記事はこちら。…
Overview: SimLab에서 선택한 Body에 대해 해당 Body에 포함되어 있는 전체 요소 개수를 확인하는 기능이 있습니다. 좌측 Assembly browser에서 Model 혹은 Body 선택 후 우클릭 » Details 를 선택하시면 됩니다. 만약 각 각의 Body에 대한 요소 개수를 확인하고자 하면 각 Body별로 반복 작업을 수행해야 합니다. 해당 스크립트는 각 Body에 있는 3D 요소 개수를 파악하기 위해 작성되었으며, csv 파일로 각 Body에 대한 3D 요소 개수를 출력해줍니다. 사용 방법은 아래의 내용을 참고해주시기 바랍니다. 해당 스크립트는 3D…
Introduction Effective tractor-implement systems are necessary for cultivating healthy crops. Traditionally, improving tractor-implement performance has relied on field testing – a process which is time-consuming, weather-dependent, and costly. In this article, we explore how MotionSolve (Multibody Dynamics) and EDEM…
AbaqusCAE에서 인식되는 1D 요소인 *KINEMATIC를 생성하기 위해선 *KINEMATIC COUPLING로 생성되는 RBE2가 아닌 constraint로 생성해주셔야 합니다. 참고로 constraint라는 entity는 HyperMesh 2022버전 이후 생긴 Abaqus 인터페이스 키워드 중 하나입니다. 해당 스크립트는 기존 모델에 있는 RBE2를 constraint로 변환시켜 주는 스크립트로, 아래의 순서로 사용합니다. Abaqus 인터페이스의 HyperMesh 실행 후 적용할 모델 불러오기 상단 File » Load » Script(Tcl/Tk) 클릭 후…
Overview: Attached to this post you will find the source code and the compiled dll/so file for the calculation of some of the most common collision metrics. These metrics include the collision energy loss, duration and relative velocity. You can learn more about how the energy loss is calculated in this post. Prerequisite:…
Overview: Short pdf with a collection of information, exercises and tools to bring you up and running especially - but not only - as experienced user of the classic HyperMesh interface: Slide #2: Finding your Tools and Functionality Slide #3: Getting Started through Youtube exercises Slide #4: Further Sources of…
Overview: This is a script that can be run at once when there are multiple solutions that need to be interpreted. How To : Step 1) Check the analysis list you set in SimLab GUI. (ex. Steady, Steady_2_inlet++) Step 2) Define the analysis case you want to run. Step 3) Enter the path where you want to save the .slb file. Step…
