CADFEKO critical error pk_error_tag_limit_exceeded when creating many unit cells via Lua macro
Hi, I am using a Lua macro in CADFEKO to programmatically generate a large periodic structure for multiport analysis. The geometry creation involves operations such as creating patches, vias, and assigning edge ports. The script works correctly for smaller models, but when the total model becomes sufficiently large,…

[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…

Stress relaxation in topology optimization
Hi, Does OptiStruct apply a stress relaxation for elements of a lower density in order to avoid highly stressed elements which don´t contribute much to the structural response? This is of interest for example when stress or strain constraints are applied or if my objective is to minimize the maximum stresses. I can not…

How does the fatigue constraint influence the topology optimization result?
Hi, I was wondering how the fatigue constraint, which can be set in the DTPL card for a topology optimization, influences the topology optimization result. In the out. file, I can tell that no sensitivities are calculated for the fatigue constraint, only a check is included. However, the final result with/without fatigue…
