A space for simulation related technical resources and discussions.
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 simulations. More precisely both SMP (-nt) and SPMD (-np) options are available. See Altair Radioss Parallel Computing Methods Latest ©Intel CPU generations are equipped with both Performance and Efficient cores (P-cores and E-cores) like for…
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…
