Reimagining Fluid Dynamics: Intuitive Design Meets Power and Precision Altair HyperMesh-CFD 2023 is tailored for those who demand both precision and efficiency in computational fluid dynamics (CFD) technology. Through a thoughtfully designed solution-centric interface, users will discover not just enhanced features, but a…
Fellow community user @Mandy Kramer sent a HyperWorks forum question seeking guidance on how to identify and correct realization troubles for seam-quad LTB connectors. With their permission, I put this Knowledge Article together with a few best practices. Hope this is useful! This article includes: * A presentation,…
MQTT Communication Library The MQTT Library establishes communication between Compose and your devices over the Internet using the MQTT protocol. MQTT is a kind of lightweight IoT messaging Protocol based on the Subscribe/publish model, which enables auto messaging from a publisher to the different subscribers.…
In this tutorial, we’ll show you how to import an Altium Designer Schematic into PollEx Logic. PollEx Logic doesn’t read binary *.SchDoc files so the schematic needs to be “Saved As” an “Advanced Schematic ascii” format as shown in Figure 1. Figure 1. Save as “Advanced Schematic ascii” PollEx also doesn’t get the netlist…
Continuing to build on more than 25 years of innovation, Altair OptiStruct™ is used globally by industry-leading companies to drive design with optimization and validate structural performance. The latest release of Altair OptiStruct™ - Altair's optimization-enabled structural analysis tool - now offers extensive…
Stress constraint for topology optimization (referred to as DTPL stress constraint) has been available in Optistruct since version 8.0. This stress constraint is defined through the STRESS field in the DTPL bulk data card of the topology design variable. It is limited to a single value of von Mises stress for the entire…
Tree geometry provides a unique challenge to preprocessing due to the relative size of the members; for example, the trunk is rather large compared to the tips of the branches which comes to a fine point. Placing an acceptable mesh – balancing between quality and quantity of the elements – across the model is not a trivial…
The signal processing OML library contains more than 60 functions that you can leverage in Compose. Some of these will help you design and test both digital and analogue filters. The task for this challenge is to design and validate several types of finite impulse response (FIR) filters. Namely: * Lowpass filter with…
Vibrating separators are used in various industries to separate mixtures of dry and wet/dry particles on a large scale. In many cases, it is cost-effective to establish and optimize process parameters that influence machine throughput and efficacy using a CAE model, rather than physical trials in a production plant or lab…
Learning how to navigate through the PSIM switch model options One of PSIM's main advantages, aside from its speed and robustness, is its flexibility. This flexibility allows you to reuse the same schematic to run simulations with different levels of fidelity and/or varying application goals. Your main allies in this…
