Correlation between
EFD and CFD

Ensuring reliability of correlation of CFD by use of extensive archives of tank test results

Design Process Prior to Tank Test

Standard
performance
prediction

- Utilizing database of tank test result archives
- Implementation of tank test

The standard process includes high risk of retesting which causes
increase of cost and delay of full scale ship construction.

CFD
Utilization

Ship hull form is evaluated immediately after the detrmination of the form

Risk of re-testing is lower. Newbuilding with a optimal
hull form is enable reducing costs

Prospects

Automatic hull form optimization

What is CFD?・・・

Abbreviation for High Performance Computing.
The use of a large, high-performance computer system to perform a process that requires a huge number of calculations.

What is HPC?・・・

Abbreviation for High Performance Computing.
The use of a large, high-performance computer system to perform a process that requires a huge number of calculations.
Also, the field of research on the theory and technology for constructing and operating such systems.

(Reference; “IT Dictionary”)

What is cluster system?・・・

A system in which multiple computers are connected behave as if they were a single
computer to users and other computers. The construction of such a system is called “clustering”.
