A space for simulation related technical resources and discussions.
In HyperMesh we use the Element Quality view to review the element quality. To enable the Element Quality view, click on the View Controls toolbar and select Element Quality. If you want to check the time step for the model of an explicit analysis, you need a criteria file in which the time step criterion has been defined.…
The JOHNSON-HOLMQUIST-CONCRETE material law is a very interesting material law for concrete modeling, especially for defense applications. This material law has been implemented in Radioss V2024.1. This material law is available with the non-local regularization; this is particulary interesting to have mesh-independant…
右側に添付のBIW.h3dとmodes16_for.tclを同じフォルダに置き、コマンドプロンプトを起動して以下のコマンドを実行すると以下のmodes16.gifが出力されます。hw.exeまでのパスは環境に合わせて変更してください。 "C:\Program Files\Altair\2024\hwdesktop\hw\bin\win64\hw.exe" -b -tcl modes16_for.tcl コードは以下になります。 hwc delete session hwc hwd window type=HyperView hwc hwd page current layout=15 for {set i 1} {$i<17} {incr…
Altair Compose is a tool that can enhance our usage of other simulation tools. In this small post I will show you how you can use it to run many multibody systems simulations in batch using MotionSolve, Altair’s multibody dynamics solver. Concretely, this example shows how to take an input model (MDL file) and change an…
The OpenRadioss Community is delighted to be invited to Philadelphia USA by Elham Sahraei, Associate Professor, Department of Mechanical Engineering, Temple University, and the center of excellence for the safety of electric vehicle battery packs. Check-out the Agenda and Register here today to join us in-person or on-line…
This article is a collection of the questions which we collected through support requests for usage of Python from HyperMesh 2024, and which are not documented yet in the online help. How can I access the data in the collections created by HyperMesh apart of using loops? The collection can be turned into a list. It can be…
Holistic System Level Approach We've all experienced a washing machine vibrating, sometimes even "walking" across the floor as if it was a living thing. In this blog, we'll explore how you can identify and possibly mitigate these annoying vibrations when designing such systems with Altair tools. [click play to watch] This…
Conveyor belts are utilized globally for various purposes, including transportation, assembly, and manufacturing. In MotionView, we provide both the belt/pulley tool and the track system tool, each designed to facilitate the creation of belt systems. Once a belt is set up using these tools, it interacts with other belt and…

For models that include multiple and large flexbodies. When animating the H3D file, it contains additional flexbody data (features & spiders). This uses resources (animations take longer to process) and makes the display rather cluttered. To reduce the impact the flexbodies h3d has on the resultant animation size, use the…
