FLOW-3D는 오늘날 복잡한 자유 표면 및 제한된 흐름 문제를 분석하는 데 사용할 수 있는 가장 강력한 도구 중 하나입니다. 사용하기 쉬운 모델링 인터페이스를 제공하며 지난 15년 이상 제가 작업한 수력 발전, 환경, 수자원 및 처리 관련 프로젝트의 설계에 필수적인 도구였습니다. Flow Science의 기술 지원 팀과 개발자는 함께 작업하기 쉽고, 조언을 제공하고, 코드의 잠재적 개선 사항에 대한 사용자의 의견을 듣고, 발생하는 문제를 신속하게 해결하고자 합니다. Flow Science의 전체 팀은 함께 일하기에 훌륭했고 모든 엔지니어에게 훌륭한 자원입니다.

FLOW-3D is one of the most powerful tools available to analyze complex free surface and confined flow problems out there today. It provides an easy-to-use modeling interface and has been an integral tool in the design of hydroelectric, environmental, water resource and treatment related projects I’ve worked on over the last 15+ years. Flow Science’s technical support team and developers are easy to work with and are eager to provide advice, hear input from its users on potential enhancements to the code as well as quickly resolving issues that arise. The entire team at Flow Science have been great to work with and are a great resource to all engineers.
FLOW-3D CAST는 우리의 품질 프로그램에 엄청난 자산이었습니다. 6가지 주조 시뮬레이션 소프트웨어를 평가한 후 Howell Foundry는 FLOW-3D CAST를 구매하기로 결정했습니다. 이 결정의 일부 요인에는 설정 다양성, 비용 및 가장 중요한 시뮬레이션의 현실 정확도가 포함됩니다. 업데이트된 결과 뷰어와 결합된 FLOW-3D CAST 의 강력한 시뮬레이션 기능은 가장 복잡한 작업에서 특히 첫 번째 타설에서 고품질 주조를 보장하는 데 도움이 되었습니다.

FLOW-3D CAST has been a tremendous asset to our quality program. After having evaluated six different casting simulation software, Howell Foundry made the decision to purchase FLOW-3D CAST. Some of the factors in this decision include its setup versatility, cost, and most importantly its accuracy of the simulation to reality. FLOW-3D CAST’s powerful simulation ability coupled with its updated results viewer has been especially helpful on our most complex jobs to make sure we have a quality casting on the first pour.
우리는 FLOW-3D를 사용하여 지난 20년 동안 많은 소모성 발사체 시스템에 대한 추진제 슬로시 및 풀스루 시뮬레이션을 개발했습니다. 보다 최근에는 Flow Science 지원 직원이 차량 기동으로 인한 ullage collapse effects를 포착하기 위해 극저온 추진제 탱크 시뮬레이션에 열 전달을 추가하는 데 중요한 역할을 했습니다.

We have used FLOW-3D to develop propellant slosh and pull-through simulations for a number of expendable launch vehicle systems over the last 20 years. More recently, the Flow Science support staff has been instrumental in helping us add heat transfer to cryogenic propellant tank simulations in order to capture ullage collapse effects due to vehicle maneuvers.
저는 연구 및 산업 응용 분야에서 유체 흐름 문제를 해결하는 데 15년 이상 FLOW-3D를 사용해 왔습니다 . 우리는 강 및 해안 구조물, 수처리 장치, 댐, 여수로, 깊은 터널 및 CSO 전환 구조물의 설계에 이 소프트웨어를 광범위하게 사용합니다. FLOW-3D는 수치 솔버 기술, 클라우드 컴퓨팅, 전처리 및 후처리 도구의 최신 기술을 통합하여 고객에게 상당한 시간과 비용을 절감합니다. FLOW-3D 영업 및 기술 지원 팀은 훌륭합니다!

I have used FLOW-3D for over 15 years solving fluid flow problems in research and industrial applications. We use the software extensively in the design of river and coastal structures, water treatment units, dams, spillways, deep tunnels, and CSO diversion structures. FLOW-3D integrates state of the art in numerical solver techniques, cloud computing, pre- and post-processing tools resulting in substantial time and cost savings to our clients. FLOW-3D sales and technical support teams are excellent!
FLOW-3D 는 다른 소프트웨어로 시각화하거나 정량화하기 어려운 복잡한 유압 문제에 대한 통찰력을 제공하는 정교한 도구입니다. 정교함에도 불구하고 소프트웨어는 매우 사용자 친화적이며 Flow Science는 훌륭한 문서와 기술 지원을 제공합니다. FLOW-3D 모델 에서 얻은 결과는고객과 사내 비모델러 모두에게 깊은 인상을 남겼습니다.
 
FLOW-3D is a sophisticated tool that provides insight into complex hydraulic problems that would be difficult to visualize or quantify with other software. Despite the sophistication, the software is very user friendly, and Flow Science provide great documentation and technical support. The results we have obtained from our FLOW-3D models have impressed both our clients and non-modelers in-house.
4C-Technologies에서 우리는 거의 35년 동안 다양한 소프트웨어 흐름 시뮬레이션 솔루션을 사용하는 선구자였습니다. 다양한 금속 합금으로 주조된 HPDC 부품에서 부품 설계 및 도구/러너 설계를 최적화합니다. 2008년부터 우리는 FLOW-3D를 사용하여 지금까지 최고의 정확도를 제공하는 것으로 나타났습니다. 또한 FLOW-3D 팀 의 지원은 탁월합니다.

At 4C-Technologies we have been pioneers in using various software flow simulation solutions for nearly 35 years. We optimize part designs and tool/runner designs on casted HPDC parts in various metal alloys. Since 2008 we have solely been using FLOW-3D as it turned out to give by far the best accuracy. Furthermore, the support from the FLOW-3D team is outstanding.
20년 이상 FLOW-3D 와 함께 CFD 분석을 사용하면서 우리의 신뢰 수준은 이제 일반 연구 목적 및 최종 설계 응용 프로그램에 CFD 모델링을 사용하는 데 확신을 가질 정도로 높아졌습니다. 이 소프트웨어는 개념적 세부 사항과 구성을 신속하게 변경할 수 있는 유연성을 제공하여 설계를 단계적으로 진행할 수 있도록 합니다.

From using CFD analysis with FLOW-3D for over twenty years, our level of trust has increased to the point that we are now confident in using CFD modeling for general study purposes and final design applications. The software gives us flexibility to quickly change conceptual details and configurations allowing the design to advance in stages.
우리는 FLOW-3D AM을 사용하여 기초 과학의 경계를 발전시켜 왔습니다 . FLOW-3D AM은 다중 합금 3D 프린팅 중 복잡한 현상을 지배하는 물리학에 대한 우리의 가설을 테스트하는 훌륭한 도구였습니다. FLOW-3D AM은 우리가 열 프로필의 진화와 관련된 물질 전달 및 복잡한 적층 구조에서 열 응력의 발달을 이해하는 데 도움이 되었습니다.

We have been using FLOW-3D AM to advance the boundaries of fundamental science. FLOW-3D AM has been a great tool to test our hypotheses about the physics governing complex phenomena during multi-alloy 3D printing. FLOW-3D AM has helped us understand the evolution of thermal profiles and the associated mass transport and development of thermal stresses in complicated additively-built structures.
FLOW-3D 는 많은 응용 프로그램이 있는 강력한 도구입니다. 우리는 FLOW-3D를 사용하여 물 전환 구조의 흐름과 수력을 효과적으로 해결했습니다. 우리는 또한 제안된 물고기 통로를 통한 물 흐름을 모델링했습니다. 우리는 정확성, 계산 속도, 특히 사용자 친화적인 GUI에 깊은 인상을 받았습니다. 그리고 우리 고객들은 모델 출력과 포스트 프로세서에 의해 생성된 애니메이션에 깊은 인상을 받았습니다. 우리는 또한 매우 반응이 좋은 지원 직원에게 감사합니다.

FLOW-3D is a powerful tool with many applications. We used FLOW-3D to effectively resolve flow through and hydraulic forces on a water diversion structure. We also modeled water flow through a proposed fish passage. We have been impressed with the accuracy, computational speed, and especially the user friendly GUI. And, our clients have been impressed with the model output, as well as, animations created by the post-processer. We are also appreciative of the highly responsive support staff.
수년에 걸쳐 FLOW-3D는 기존의 유압 모델링 도구로는 해결하기 매우 어려웠을 복잡한 유압 문제를 해결하는 데 도움을 주었습니다. 우리는 FLOW-3D 팀에게 매우 감사합니다 . 그들은 수년에 걸쳐 지속적으로 소프트웨어를 개선해 왔으며 우리의 요구에 매우 신속하게 대응해 왔습니다.

Over the years, FLOW-3D has helped us solve complex hydraulic problems that would have otherwise been very difficult to solve with conventional hydraulic modeling tools. We are very thankful to the team at FLOW-3D. They have constantly been making the software better over the years, and have been very responsive to our needs.
FLOW-3D 는 당사의 우주 공학 연구 및 개발 프로세스에서 필수적인 도구입니다. FLOW-3D는 극저온 연료 역학의 프로세스를 더 잘 이해하여 질량을 줄이고 발사기 성능을 향상시키는데 도움이 됩니다.

FLOW-3D is an essential tool in our space engineering research & development process. FLOW-3D helps us better understand processes in cryogenic fuel dynamics, leading to savings in mass and improved launcher performance.
FLOW-3D CAST는 CASTMAN, Inc의 제품 개발 및 품질 확보에 매우 큰 도움을 주었습니다. FLOW-3D를 한국에 독점 공급하는 (주)에스티아이씨앤디의 수치해석 컨설팅팀과 협업을 통해 제품 개발 시 FLOW-3D 주조 시뮬레이션을 통해 기술적인 여러 어려움이 있는 제품 개발에 모두 성공하였습니다. 이는 개발 비용, 기술적인 어려움, 개발 기간 및 가장 중요한 시뮬레이션의 정확도가 포함됩니다. FLOW-3D CAST 의 강력한 시뮬레이션 기능은 가장 복잡한 작업에서 고품질 주조를 보장하는 데 도움이 되었습니다.
