Overview Classic Models (.dmod) extract use templates to extract data from a specific report at a time. Classic Models can also acquire data from structured sources like Excel, CSV, and Database sources. Classic models may include filters, sorts, calculated fields, lookup fields, and summary aggregations. Data Prep Studio…
Overview This Plot Macro will create a new curve that has a cleaned up X-vector based on selected original curves, that have an overlap in X. So the new curves' X-vectors are continuously increasing. Pre-Requisite Plot Macros can be loaded through preference files, as the example attached. To reference the preference file,…
Overview In Radioss as in other solvers, forces are frequently output by component (X, Y Z). Even if in Radioss many forces now allow direct access to normal and shear forces as extra outputs, there are still some cases (eg: Radioss TYPE13 or TYPE25 springs) where the user needs to compute the shear force. The attached…
Overview 本記事では、永久磁石同期モーター（PMSM）のセンサレス制御を例に、AI・機械学習をパワーエレクトロニクス分野に適用する方法を検討します。 機械学習による動的サロゲートモデル作成ツールのAltair romAIを用いて、モータの電流と指令電圧値（Id, Iq, Vd_ref, Vq_ref）を用いて、ローターの角速度と磁極位置を予測するモデルを作成しました。 この予測モデルをパワーエレクトロニクスAltair PSIMのPMSMモータドライブに組み込みました。実際のローターの角速度と磁極位置の代わりに、予測したローターの角速度と磁極位置でモーター制御を行うよう変更しています。 ローター速度（wm,…
Overview This Extension provides a toolbar with buttons to turn the "Axis LockGuard" ON/OFF (available since HG2023.1). The TCL commands that are used in the background are: [::hwplot::GetPlotManagerHandle] SetFitAxesLockGuard true [::hwplot::GetPlotManagerHandle] SetFitAxesLockGuard false Pre-Requisite Download and un-zip…
Overview This script extracts only the desired results from an H3D file and writes this subset into a new H3D, making it easier and faster to manipulate results in subsequent steps of a workflow. Usage/Installation Instructions To extract a subset of results into a new H3D file, run this OML script in Altair Compose and…
Overview These are the files loaded and saved in HyperMesh 2023 in the playlist HyperMesh 2023 - Basic Preprocessing. Use these files to follow what is demonstrated in the videos. The pdf file embeds the videos and adds links to further content, and a keyboard template. Usage/Installation Instructions Download and unzip…
Overview Purpose For the automotive and heavy equipment industries, tire-soil contact area and sinkage are highly relevant since they allow engineers to predict Tractor performance at field applications, allowing the analysis of parameters such as traction, slip and fuel efficiency. It is possible to reduce the need of…
