Accessing Statistically-Based Design-Allowable Properties Using MMPDS Data in AMDC
In finite element analysis (FEA), the accuracy of your simulation is only as good as the input data - particularly the material properties. In safety-critical applications such as aerospace, defense, and automotive, using nominal or average material properties is not enough. These values don’t account for natural…

Is there an efficient way to simulate a 1.5m aluminum (200um rms) reflector at sub-THz frequencies?
Description: Hi there, the issue I'm having is that I've been using the LE-PO solver, but it doesn't work for lossy materials such as aluminum surfaces. I'm specifically trying to obtain a model that accounts for the surface material and surface roughness (200um for example) seen when using a horn-fed dish (single…

Particles disappear
Hi, I am doing a simulation of a ramp that vibrates and has particles. The issue I am having is that when the ramp starts to vibrate, after 0.05s the particles disappear. I have tried reducing the Rayleigh Timestep/ Percentage, but this keeps happening. Is there any other reason why particles might be disappearing and how…

Magnetic-Transient solve stops with “ill-connected elements” although mesh check is clean
Hi everyone, I’m modelling an axial-flux machine (AFM) in SimLab 2025. My CAD is imported as a STEP file and meshed inside SimLab. I have already run three transient magnetic simulations successfully; the only difference between them was the magnet arrangement on the rotor. After applying a new magnet pattern the solve now…

Shrinkage, Particle Size Distributions, and contact Radius
Hi Everyone, I am wondering how EDEM handles the contact radius and if it is possible to achieve my goal with some work-arounds. First of all, I understand that a contact pair is registered if particles have contact radius overlap: triggering the calculateforce() function. Now what I dont understand is what are the…
