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.

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

- 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”.
