Is there any way to simulate an infinitely periodic ground with a single antenna.
Description: I am trying to simulate a single antenna above an in-homogeneous soil. Currently I have an antenna placed above a checkerboard of solid blocks of soil, and I want to tile this out to infinity. When trying to implement infinite periodic boundary conditions, or expanding it as an array, the system always tiles…

Suspension Travel lock
Hello Adams, I tried adding a bump stop to hard-stop the suspension travel. My suspension can travel up to 50 mm in jounce and 50 mm in rebound. To simulate the same scenario, I set the jounce travel to 60 mm and checked whether the suspension stops at 50 mm. As a result, the suspension exceeded 50 mm, and the shock began…

[Linear Static] Inertia Relief를 이용한 Stress 결과에 대한 문의 건
안녕하세요. 응력해석 업무을 시작한지 1년 정도 되었습니다. INREF 를 이용한 Linear Static 해석 결과에 대해 문의사항이 있어 질문드립니다. 제가 알기로는 Linear Static은 F = K x u 를 바탕으로 K 강성 값을 계산하고, 변위 u 값을 구하여 도출한 u값을 이용해 strain " (u2-u1) / u1 " 을 구하고, Stress " Elastic Modulus x strain " 을 도출하 는 것으로 이해하고 있습니다. 그러나 Inertia Relief 의 변위값(u)은 실제 변위값과는 무관하게, 변위를 제어하도록 해당 노드들에 가속도 를…
