A three-point bending flexural test is a standard test in which a specimen is loaded under uniaxial bending stress. The test is performed to obtain material properties such as elastic modulus in bending, stress-strain behavior, and failure limits. Some standards are used for this test. For example, ASTM D790 or ISO 178 are…
Constraint lines in S-FRAME Analysis provide an efficient method for defining connections between panels and walls. Part 2 of this webinar series* explains how and why you should use the Constraint Line tool in S-FRAME Analysis. Watch to learn about: * Rigid Constraint Lines – used to connect shell elements that may not…
Extracting Design Forces using Wall and Strip Integration Lines in S-FRAME Wall Integration Lines, Strip Integration Lines, and Constraint Lines: what are the benefits and how are they used? Integration and Constraint lines are efficient tools when analyzing and designing walls and slabs. This two-part webinar series…
We are often asked how to represent steel decks in S-FRAME and wanted to provide a road map for those looking to do just that. Assume we have a steel deck that we wish to analyze in S-FRAME. It is important to use accurate material properties to represent the stiffness of the steel deck. We can work with the information…
This article gives more information regarding the concept of ports and sources in CADFEKO. What is a port in CADFEKO To cause current to flow in a model, you need to excite or illuminate a model. A port is a mathematical representation of where energy can enter (source) or leave a model (sink). Define a port where you want…
Abstract In this article we will use a novel AI-based application, romAITM, to generate a Reduced-Order-Model (ROM) from a large database of static simulations and optimize their parameters. We will demonstrate how this innovative approach can support the design of an Aircraft Wing. The romAI model will be used to estimate…
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…

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…
