오늘에야 알았다. FDS 변수가 이렇게 많다니... 기억을 다시 되살려서, 아래의 변수들에 친해지고 싶다.. 자주 쓰는 것들은 알겠는데, 어떤 건 많이 생소하다. 자주 봐서 익혀야지.. 많다. 참 많다. 17.1 BNDF (Boundary File Parameters) Table 17.1: For more information see Section 16.5.

Smokeview korean edition

화재 해석 프로그램 중에 Smokeview 라는 프로그램이 있음..

이 프로그램은 NIST 에서 개발한 프리 해석툴인데

영어인게 흠 아닌 흠 ^^

그것 땜시, 영어가 달리는 유저들이 고생하고 있음... 특히 한국에서..

그리하여, 영어 메뉴를 한글화 해보기로 함..

짜잔,, 그 결과..

제공되는 소스가 전체 다를 포괄한게 아니라서

일부는 그대로 영어로 나오지만,

대부분은 한글화에 성공함..

ㅎㅎ, 괜찮은데...

Thermotun 7.1 과 Pipenet 1.1 릴리즈 노트

Thermotun 프로그램을 사용한지도 어언 9년 정도 되어가는 것 같다.

처음에는 버전 5 를 사용하다 6 으로 7 로 변하였다.

감회가 새로운 것은

이 프로그램의 버그 문제 수정에 대해 3가지 정도 기여했다는 점이다.

이 프로그램은 영국의 던디대학교의 바디 교수가 만든 프로그램인데

터널 시스템내의 공기압 및 열환경 해석에 있어 나름 스페셜한 프로그램이다.

물론 나도 이 프로그램을 잘 다루고 있지만, 아직 부족한 것도 사실이다.

아래에는 이 프로그램의 그간 개발 과정이 담긴 릴리즈 노트를 담았다.

아~ 이 프로그램 배우러 영국 스코틀랜드로 갔었던 일주일간의 추억이 떠오른다.

넓은 들판,, 막 기사가 말타고 튀어나올것 같은 그 들판.

보는 곳마다, 역사가 서려있는 뭐랄까 암튼 분위기 짱.

다시 가고 싶다.

QRA 의 미래..

QRA 가 나아갈 길은 정해져 있다.

사라지거나, 발전해서 살아남거나..

지금처럼의 방식이라면 자충수로 자멸할 것이다.

대신 발전책이 있다.

모든 위험은 언젠가는 발생한다.

사람은 태어나서 죽고, 건물은 지으면 무너진다.

모든 자연계의 섭리는 엔트로피 증대의 법칙 속에서 지배를 받기 때문이다.

불이 안나게 할 수도 없고, 지진이 안 일어나게 막을 수도 없다.

그렇다면, 지금의 과거의 해를 통한 빈도의 문제에도 자유롭고, 시나리오 구성에도 자유롭고, 기준의 문제에도 자유롭고 이를 통해 안전은 더 확보할 수 있는 방법이 있다.

QRA 에 대한 단상

이전 글을 보다 보니, 전에는 느끼지 못한 것들이 보이기 시작한다.

몇년동안 이걸 하다보니깐,

잘 못 됬다는 생각이, 논리적으로 말이 안된다는 생각이 든다. 아니 마음 깊숙히 박히게 된 것 같다.

QRA = 빈도 x 결과이다.

결과는 그래 좀 덜 정확하더라도 화재가 커지면 많이 위험한 결과가 나타날 것이고, 약하면 덜 위험하거나 안전한 결과가 나타날 것이다.

첫번째 문제점은 빈도이다.

과거의 통계를 바탕으로 한 미래 예측은 불가능하다. 그러한 통계는 허상일 뿐이다.

피난 프로그램의 간단 비교

피난 자료에 있던 내용 중 프로그램 부분만을 정리해 봤습니다. 참고들 하세요..

국내에서는 Simulex 가 대표적인 피난 툴로 사용되고 있으며, 최근 Pathfinder 가 일부 사용되고 있습니다.

그외에도 소수의 유저들이 bulidingExodus 나 Gridflow 를 사용하고 있는 듯 보이며,

여러분들이 많이 사용하고 있는 FDS 프로그램에도 자체의 Evac 기능이 있다는 것은 다들 아실 듯..

이 자료는 예전 2007년도에 카페에 올렸던 자료입니다만..

참 세월도 빠르네요. 그 땐 열정도 많았는데

지금은 에휴

암튼 못 본 분들은 참고하길 바라며 이 글을 다시 올려봅니다.

CFD 의 역사

CFD 는 고유한 역학에 비해 그리 역사가 오래 되었다고는 할 수 없습니다만.

CFD 라는 분야도 그러한 역학 계산의 한 줄기라고 한다면, 그 원 뿌리는 상당히 오래 될 수도 있습니다.

아래에는 간단히 CFD 가 어떻게 흘러왔는지에 대한 글이 있습니다. 찬찬히 잘 읽어 보기 바랍니다.

CFD 에 대한 단상..

CFD 분야의 발전은 상당한 수준까지 전개되었다..

초기의 간단한 유동과 열전달에서부터, 이제는 불도 지르고, 고속열차 주행도 시키고, 심지어 충돌시 변형도 시킨다. 분야마다 다르지만, 유체, 항공, 우주, 전자, 소음, 해양, 화공 등 거의 전체 역학 부분에 있어 CFD 의 역할 및 비중은 상당하다.

이제 서서히 조금 더 사람들에게 친숙히 다가가려 하고 있고, 그러다 보니 사람들은 CFD 는 아무나 할 수 있는 툴이 되어 버린듯하다.

그 말이 맞더라도 CFD 를 통한 협업체계가 구축되더라도, 기본적인 구성만으로 돌릴 수 있는 부분도 있고, 최고의 전문성이 함께 고려되어야 하는 부분도 있고, 그 중간의 어정쩡한 부분도 있다는 점은 간과해서는 안된다.
