What’s new in Abaqus 2023 – Contacts, constraints and material enhancements

Robust 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

What’s new in 3DExperience Fluid Mechanics Engineer FMK – 2023x

We 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

SIMULIA AMERICAS USER CONFERENCE 2023

In 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

Simulation of Magnetic Fields in MRI Machines

The 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

Scope of Simulation in Battery Cell Design and Development

Green 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

Fluid Meshing in 3DX

This 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
