The Siemens Community Catalyst program was co-created with our community to acknowledge technology leaders who consistently contribute to the Siemens Community. Nominations are accepted on a rolling basis.
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…
This post presents an Altair Radioss solution to simulating hypervelocity impacts on composite laminate. It is based on Meso-scale modeling of hypervelocity impact damage in composite laminates from Aleksandr Cherniaev & Igor Telichev, published in Composites Part B: Engineering, volume 74 (June 2015) [1]. Figure 1: Bullet…
In this white paper, a case study is presented in which a small military unit that has been deployed close to enemy forces needs to communicate beyond line of sight to call in reinforcements. To enhance resilience against jamming, the forward unit has access not only to Low Earth Orbit (LEO) satellites but also to a…
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…
In this white paper, the jamming of a radar station and of a communication link by a drone or a swarm of collaborating drones is investigated. This involves ultra-wideband antenna design in Feko and propagation analysis over terrain in WRAP.
