: 컴퓨터 시뮬레이션을 막 시작한 학생입니다.

: 저는 상용 제품이 아닌 c-언어로 프로그램을 직접 짜서 제가 연구하는 시스템(physical simulation이 현재 진행 중)을 해석하려고 합니다. 혼자 공부를 하고 있는데, 프로그래밍 언어, 시스템의 수학적 모델링 등은 쉽지는 않지만 그런데로 이해가 가는데, 3차원 그리드 생성하고 그것을 제가 짜려는 프로그램이 인식할 수 있도록 하려는데 전체적인 감이 잘 잡히지 않네요. 여러분들의 도움을 간절히 바라고 있습니다.

: 참고로 제가 다루는 방식은 FDM 혹은 FEM입니다.

: 질문을 정리하면

: 1) 어떻게 3차원 메쉬를 짤 것인가?

: 2) 여러 예들을 웹상에서 훑어보면,이들 그리드는 균일 하지않은 경우가 일반적이던데 그렇다면 무슨 기준으로 그리드 크기 분포를 결정할 것인가?

: 3) 일단 완성한 그리드를 어떤 식으로 내 프로그램에게 인식(?) 시킬 것인가?

: 관심 가져주셔서 감사합니다.
