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…
In this release, the main focus remains on expanding the coverage of the LS-DYNA input reader, a critical feature to make the code even more accessible and ease its adoption by a broader community of users. It is now possible to mix input using include files from both solver formats. We better cover options dealing with…
List of known issues that were discovered after release. (Note: This article will continuously be updated when issues are reported) HyperMesh CFD 2023.0 known issues: Geometry - Meshing * Manage tool: Manage tool in Simulation ribbon does not list meshing or runs residing in same folder as hmcfd file. Workaround: You have…
Did you know that AcuSolve offers three ways to calculate heat transfer coefficients (HTC)? 1.direct : Physics based (available via acuTherm) 2. user_ref_temp: Physics based with varying reference temperature (available via acuTherm or "Calculate" in SL/HWCFD) 3.turb_wall: Turbulent wall based (available by default, if…
