Dassault Systemes SIMULIA MODSIM Software is a comprehensive suite of simulation tools that helps manufacturers design, develop, and optimize products and processes. MODSIM provides a unified modeling and simulation environment that enables engineers to quickly and easily create and analyze complex models, perform virtual testing, and optimize designs for performance, manufacturability, and cost.
Read moreRobust convergence for rigid bodies and couplings: 2022xFD04 The reference nodes of rigid bodies and couplings are not treated as general nodes anymore for the residuals convergence. A weighted factor has been introduced in the denominator. This factor (f) has a default value of 1 if the node is not a reference node. In case of reference node, the
Read moreWe are back in with our what’s new series in 2023 and we are starting with computational fluid dynamics this time. Let’s review the offerings first from products perspective. Under the DS umbrella, CFD has two flavors: the conventional Navier Stokes based flow and the high fidelity Lattice Boltzmann based flow. The first one is available as a 3DExperience Native
Read moreIn simulation community when it’s time to learn application of software tools for real-life product development, one of the best ways to do it is to approach other users. The user meetings organized by SIMULIA once every year has similar objective: bring user community together. These meetings bring together users to share their knowledge and experience in advancing methods and
Read moreThe invention of Magnetic Resonance Imaging (MRI) machines in medical diagnosis is very interesting. Before MRI was MRI, it was called Nuclear Magnetic Resonance (NMR) that was initially demonstrated in 1945. The transformation of medical imaging from NMR to MRI is attributed to three Physicists: Dr Raymond Damadian, Paul Lauterbur and Sir Peter Mansfield. In 1969 Dr. Damadian hypothesized that
Read moreThe electric vehicle industry incepted and matured many years back with the arrival of reputed companies in this space such as Tesla, NIO, Nikola, Rivian and many more. Surprisingly the space has been dominated by the Start’Ups. The current trend seems revolutionary as more and more EV vehicles keep showing up on roads. This trend is being fueled by many
Read moreAntenna design for mobile phones has always been a challenging topic for engineers, and designing antennas to support the new 5G frequency bands will raise the bar further. Two frequency ranges are of most interest: frequency range 1 for sub 6 GHz bands communication and frequency range 2 for communication at the millimeter (mm) wave frequencies above 24 GHz. Some
Read moreGreen energy is around the corner now. In the past decade drastic climate changes have been seen everywhere around the world. Greenhouse gas emissions are the major cause of global warming and carbon di oxide emissions are responsible for 75% of all greenhouse gas emissions. With the unprecedented increase in gas prices due to geopolitical uncertainty, the fossil fuel is
Read moreThis post is a continuation of the vignettes that I started few weeks back with the Computational Fluid Dynamics theme. The vignette demonstrates how to create a CFD mesh in the 3DExperience platform. Majority of CFD pre processors require an air tight or water tight CAD geometry to create even a simple CFD mesh. The 3DX pre processor hex dominant
Read moreIts good to change for a while so that interest continues. I have been writing incessantly since years and my total blog count will soon approach one hundred. Before hitting the magic number I thought of rattling for a while by sharing vignettes. That would give me an opportunity to show something live and hands on. So the theme for
