Introduction Specific absorption rate (SAR) is a measure of the rate at which the RF energy is absorbed by the human body tissue. This is an indication of the heating effect that can be caused by the high frequency electromagnetic fields. SAR limits and regulations vary among different regions in the world. Two commonly…
Impedance added by current measurement Have you ever wondered how current is measured in PSIM? There are multiple methods for measuring current, with the most obvious ones being the Current Probe, Current Sense blocks, and the Current Flag for some components. However, there are also more unconventional ways of measuring,…
Multistory Builder (MSB) in S-FRAME The Multistory Builder (MSB) feature in S-FRAME empowers users to more strategically create models of buildings at a higher level, allowing for easy model changes, and the ability to confidently respond to design changes. * S-FRAME now employs a new grid tool for the creation of Base…
Practically, metals used in antennas and their surroundings are not perfect electric conductors. To accurately design an antenna, ohmic loss effects should be accounted for. Finite conductivity is accounted for by computing the equivalent surface impedance of the metal. It is important to note that the thickness applied to…
Altair PollEx is said to be “ECAD Agnostic”, which means it can import PCB designs from every mayor ECAD vendor. Due to how some vendors handle their file formats, some configuration must be done to import designs. In this tutorial, the steps to correctly set up PollEx to import Cadence Allegro designs are shown. * Find…
Quantities like cogging Torque are very sensitive to the mesh, so it is important to have regular mesh, extrusive mesh in 3D and make the step on the scenario corresponding to mesh element size in the airgap. In skewed topology this is not possible. For Motor with magnets on the rotor defined as a ring, it is possible to…
In this document, three examples are presented to demonstrate the convergence issues encountered in a non-linear implicit static analysis and the remedies to overcome the convergence-issues. The results presented in this document were obtained using OptiStruct version 2022.2 Example1: Snap-fit analysis to demonstrate the…
This challenge is to run a structural analysis on one of the components of the model, using the motion resultant forces as a Load case. Find the Prosthetic Knee project attached to this challenge. Run a Motion Analysis in the Motion Ribbon, open the Motion Run Settings in the Analyze Motion icon, select an end time of 2.0…
Hypermesh proposes the Boolean Operations tool to list elements/node and create new sets. You can set Boolean operations with the following types: * Union * Intersection * Union-Intersection * Remove list B from list A * Remove list A from list B This tool can be found under Aerospace->Sets->Boolean On Sets (Optistruct and…
