Introduction Hvtrans is a utility available in HyperWorks Desktop package, which allows to convert any solver native format support into h3d format. As a starting point, let’s review the motivations to convert native data in h3d: File size: Conversion helps to reduce significantly native solver output files (especially…
Altair romAI is an AI-powered technology that creates reduced order models (ROMs) to accelerate complex simulations like DEM, CFD, etc. ROMs created with romAI capture the dynamic response of a system accurately and yield almost instant results. One of the most time-consuming steps when working with romAI is preparing your…
Twin Activate is a block diagram simulation environment for modeling dynamic systems. It features several blocks that approximate non-linear functions using lookup tables, which are often useful in systems modeling. In this short guide, I want to show how N-dimensional lookup tables blocks should be used in Twin Activate…
Data Preparation and Format Conversion Now that I have all the simulation results from the DOE, they need to be formatted specifically for romAI, which requires a single CSV file with time in the first column, followed by all training signals (inputs, outputs, and states) in subsequent columns. This file contains data from…
Introduction As the world shifts toward electric solutions, battery charging technology has become a cornerstone of modern innovation. At the heart of this technology lie power converters - sophisticated devices that manage the crucial task of delivering power to batteries efficiently and safely. Designing these power…
The environment is an increasingly important concern today and no economy is unaffected. Brake dust particle emission is becoming more and more important during brake development due to upcoming legislation and manufacturer responsibility to develop “green products”. As braking is a complex process, depending on speed,…
The Flow Simulator (FS) API allows users to create a main control program to load the FS solver DLL to perform basic functions such as loading and running a model. The API can be used to couple a FS model with another solver (ex: a thermal solver for 2D or 3D parts) The following features are currently available in FS DLL:…
E-book for System Dynamics and Controls Using Altair Compose This e-book is aimed at readers who are approaching “System Dynamics and Control Theory” for the first time or have a basic knowledge of this subject. We will provide the reader all the required theoretical knowledge before moving to the practical examples shown.…
S-FRAME stores and displays different steel section databases, letting the user decide which sections are more fitting to represent and try different conditions. In common practice, the user tends to use these default databases, however, some projects and models require using sections with specific properties, outside of…
This white paper discusses simulations of antennas on a large airplane for cases in which the inclusion of creeping waves is important: antenna patterns that include the shadow region of the fuselage and coupling between antennas on opposite sides of the fuselage. Results obtained with the asymptotic method Faceted Uniform…
