A space for simulation related technical resources and discussions.
An efficient workflow to follow when dealing with complex and/or dirty CAD models with numerous solid parts and numerous small details is as follows: 1) Delete all unnecessary parts 2) Delete any Bolts&Logos using the Geometry>Cleanup>Defeature tool 3) Make sure there are no big gaps/holes in the model. For this we usually…
You need powerful tools for motor drive design, simulation, and analysis. Altair provides them. We achieve the fastest and most accurate simulations on the market that will make your work more efficient than ever. Key challenges that engineers often face in motor drives include: * Motor performance evaluation * Controller…
Since 2016 PSIM has supported a link with SPICE, but what does this mean? What you can do. The simple explanation is that you can decide to use a spice engine to run a simulation that has been built using the PSIM schematic editor, but there is no co-simulation between the PSIM engine and SPICE. Here is a tutorial video to…
When building a CAE model, there are a lot of information you should input in order to successfully run your analysis and of course, to have reasonable results. In this article we will show a couple of tools and features we have available within HyperWorks and OptiStruct to validate your model and avoid error messages and…
Use case The plane strain formulation assumes that the strains in the plane perpendicular to the axis (or simply out-of-plane) are zero or irrelevant. When running a CAE analysis, using the plane strain assumption can lead to considerable savings in computational time and file storage. The simplification to a 2D mesh also…
Altair commitments As a starter, some of the modifications changed the way we write the inp file. Our choices for the format of the inp file are driven by development decisions, considering not only Abaqus, but also the consistency and the ease of conversion with other solvers supported in HyperMesh. As Abaqus supports…
As we introduced several significant changes for Abaqus in 2022, the article below isolates form the general release notes the improvments that are related to Abaqus. 2022.3 Significant changes: Enhancements * Sub-Categories for Load Collectors in Abaqus Interface Load collectors are now organized into sub-categories in…
This article is a practical guide on how to feed a microstrip patch antenna on a finite ground using a pin feed. As an example, we will look at a microstrip patch antenna fed by a coaxial cable via an SMA connector from below the patch. The front and side (section) view of the physical microstrip patch antenna for…
This article is a practical guide on how to feed a microstrip patch antenna on an infinite ground using an edge feed. As an example, we will have a look at a microstrip patch antenna fed by a coaxial cable via an SMA connector connected to a feed line. The front and side (section) view of the physical microstrip patch…
This article is a practical guide on how to feed a microstrip patch antenna on a finite ground using a waveguide source. As an example, we will look at a microstrip circular patch antenna with a feed line connected by an SMA connector to a coaxial cable. The front and side (section) view of the physical microstrip patch…
