A space for simulation related technical resources and discussions.
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…
Let’s have a look at the key features and improvements of Altair® Flux® 2023! Electromechanical design is key in all electrification projects and Flux is the perfect tool to optimize the efficiency of the power conversion. Whether you are designing electric machines, actuators, or busbars for power converters, Flux 2023…

Changes in the file format In Altair PSIM v2022.x a new file format is used for thermal models. In v2021, device thermal models were stored in a proprietary binary format (.dev). In the current release a “.xml” file is used with the following characteristics: * Can be edited both with PcdEditor and any text editor. * Only…
How to create a variable capacitor in PSIM Following the adaptations of variable resistors and inductors within PSIM, this article focuses on the creation of a variable capacitor model. This model will allow the users to navigate between different capacitances and even utilize cap value look-up tables in a structured…
