A space for simulation related technical resources and discussions.
From the part browser, several predefined configurations are available ; and one of them is named 'Tetra 5mm'. But, during your first tries, you might encounter an annoying behavior and get this kind of error message: To make it work, the PDM MeshFlag attribute of your part should be set to SMT (Solid Mesh Tetra) or SMH…
This white paper discusses the comparison process and script used to compare baseline and optimized models of an engine cradle.
An Introductory Webinar to Morfeo by Cenaero - Now Available Through the Altair Partner Alliance. Morfeo is a powerful software that relies on several dedicated libraries written in C++ for mesh management, mesh adaptation, material behavior, finite element features, solvers, and parallelism. With its extended finite…
NONLINEAR HARDENING MODELLING IN OPTISTRUCT Strain hardening is the process that makes a material harder and stronger as a result of plastic deformation. In general, plastic deformation moves existing microstructural dislocations in the material and generates additional ones which result in a reduction of ductility and…
Studied device This study case is devoted to the modeling and analysis of an axial flux machine with one internal rotor and two external stators. The motor geometry and meshing description are defined by using the AFM modeling tool, as shown below Basic EM analysis All physics definitions of the motor can be realized by…
Studied device The studied device, a synchronous reluctance motor, is running in motor mode. As presented in the figure below, it includes the following elements: * a fixed part (stator) including yoke, slots, and windings * an air gap * a movable part (rotor) with flux barriers Basic EM analysis All physics definitions of…
Altairのプレス成形シミュレーションの開発ロードマップでは、HyperFormからInspire Formへの移行が推奨されておりますが、その移行がすべてのHyperFormのユーザー様にとって最善の選択という事ではないようです。 Inspire Formという選択 HyperFormはHyperMesh（HyperWorks）環境でのプレス成形CAEシミュレーション業務を行われるユーザー様にとって最善の選択であることに間違いありません。 しかしながら、プレス成形CAEシミュレーション業務を行われているユーザー様にとっては、HyperFormは今後機能面やコストアップなどの問題が発生する可能性があります。…
In case you run into problems during the setup of a linear analysis with Optistruct, please use the attached document as a starting point for debugging.
Sometimes, Altair Support will ask you to provide debug logs for licensing. This articles gives step by step explanations to provide the required logs on Linux. * Open a terminal window * Enter the three following commands: export ALM_LOG_ENABLED=1 export ALM_LOG_LEVEL=debug export ALM_LOG_FACILITY=file:/tmp/alm.log Note:…
This article is an overview of the new and improved next-generation CADFEKO 2022.3, based on the familiar interface of legacy CADFEKO. CADFEKO has been refactored to include an improved graphical user interface, effective workflows and many new features. Note that changes were also made to the next-generation CADFEKO API…
