Altair® EDEM™ is available on Altair One and continues to prove its market leadership by setting the industry standard for the Discrete Element Method (DEM). Now more powerful and easier to use than ever - EDEM 2024.1 sees the addition of concave polyhedral particles enabling users to reproduce more complex physics when…
Feko's Schematic Link feature is a useful tool for creating realistic connections between MTL cables and the 3D environment. It is possible to connect the cable directly to geometry parts as well as to MoM ports. The video shows the complete workflow for the second case.
The High Frequency Electromagnetics (HFEM) Toolbox is a library dedicated for post-processing Altair Feko data, for example, far field, near field and impedance data in Altair Compose. Field calculators are available which allow ease of access to the data of derived electromagnetic quantities, for example, left and…
Use the ConvertLuaScript utility to migrate legacy CADFEKO Lua scripts to the latest CADFEKO API format. Migration is only applicable to CADFEKO Lua scripts created prior to version 2022.1 (it is not applicable to POSTFEKO scripts). Instructions * Download the attached utility for your system (available for Microsoft…
In metal plasticity, typically only the deviatoric stress is the cause of yielding. Plotting the yield surface in principal stress space, will result in a cylinder whose axis is the hydrostatic pressure line. This indicates that yielding is independent of the hydrostatic stress state, which means that we could have…
Overview This article presents different methods for modelling emergency landing systems using Radioss monitored volumes. The loadcase here is the impact of a vehicle on the ground with an initial velocity. Several approaches are used to model the balloons’ behavior and can be compared: * Uniform Pressure Sub-Chambers…
Even though the majority of Radioss formulations/keywords are available to be set up through HyperMesh pre-processor, some will only be available in future versions of the graphical interface. However, there are still ways to handle these unsupported keywords through HyperMesh, to make the model setup and changes. In this…
In this video we will explore the different pad reinforcement layout types and how they can be configured to match our requirements.
Radioss is supporting multi-threading and multi-processor options to speed up the simulation. More precisely both SMP (-nt) and SPMD (-np) options are available. ©Intel new CPU generations are equipped with both Performance and Efficient cores (P-cores and E-cores) like for instance 12th (Alder Lake) and 13th (Raptor Lake)…
The file "RTTCalculator.dll" is removed from the PSIM setup for versions PSIM2024 and PSIM2024.1. If your PSIM schematic contains JMAG-RT blocks, when running simulation, you will encounter an error message: Error: Failed to load "RTTCalculator.dll, error - 126. To run JMAG-RT examples, one needs the file…
