Inspire 강제 종료 현상
안녕하세요? 인스파이어 2025를 실행해서 조작하다보면 갑자기 인스파이어가 꺼져버립니다. 특히 OptiStruct으로 해석한 후 해석결과를 열어볼때 거의 100% 꺼져버립니다. Simsolid로는 해석도 되고 결과파일도 열어볼수 있습니다. 심솔리드로 해석한 후에 위상최적화를 진행하고 결과도 볼수 있는데 다시 위상최적화 한 결과에서 구조해석을 하면 또 죽어버립니다. 첨부의 그림은 인스파이어가 설치된 컴퓨터정보이고 첨부의 STMOD화일에서 옵티스트럭으로 해석을 진행한후 결과를 열면 인스파이어가 즉시 종료됩니다. 그래픽카드를 오늘 다시 최신버전으로 클린설치를 했는데 동일하네요.…

PSIM 학생용 라이선스 비활성화 오류 및 초기화 요청
PSIM 학생용 라이선스를 사용하고 있습니다. 기존 데스크톱에서 사용하던 라이선스를 노트북으로 이전하기 위해 비활성화를 시도했으나, 다음과 같은 오류가 발생합니다. "Error deactivating license: Cannot deactivate license order" 이전에 라이선스를 여러 번 비활성화하고 재활성화한 이력이 있습니다. 혹시 비활성화 횟수 제한에 도달한 것인지 확인 부탁드립니다. 가능하다면 기존 라이선스의 활성화 기록을 초기화하여 노트북에서 다시 사용할 수 있도록 도움 부탁드립니다. 감사합니다.
