aeroelasticity of a Formula 1 front wing
Hi everyone, I’d like to do a not-too-complicated aeroelasticity study of a Formula 1 wing I found online with a linear static FEM. This is the procedure I’d like to follow, but I’m not sure how to handle one step: Perform a CFD analysis of the wing Extract the pressure field around the wing Import the CAD into HyperMesh…

Quality Check Criteria
Just noticed something that is troubling me. When looking at Element Quality in 2025 version of HyperMesh/Optistruct, in the Criteria display, even though I have set the criteria in the Criteria Editor, the Iso plots in "Criteria" don't use the same Fail criteria. For example, in the image below, the aspect ratio Fail is…

SPH Components Not Visible After Simulation in Altair Radioss
I am attempting to model the soil–tool interaction using Altair Radioss. The soil bin was meshed using SPH (Smoothed Particle Hydrodynamics) particles. The input files used for the setup are attached. However, after running the simulation, the SPH components are not visible in the results. I am unable to identify the cause…

Eulerian interface type model
Dear experts, we have encountered a difficulty when using the Simlab three-phase model: It is quite difficult to understand from the manual what "smooth" and "sharp" in the Eulerian interface type model mean. Are they referring to the "level set" model? Or the Algebraic Eulerian method? Could you please provide the…

Measurement of the flux density in a fixed distance away from the rotor
Hi everyone, thanks for your patience! I have performed measurements along the rotor axis (z-direction), where the sensor moved parallel to the rotor while maintaining a constant distance from its surface. I would now like to reproduce these measurements in a simulation. How can I evaluate the magnetic flux density at a…

Contour plot of strains
I feel very embarrassed to ask since this must be an incredibly basic thing, but how do I get a contour plot of strain from HyperMesh (using results of an Optistruct model)? I can get contour plots of stress easily enough, but strain just seems to not be an option. I have tried activating the Strain Global_output_request…
