Được biết Napa cũng là một trong những phần mềm mạnh dùng trong nghanh tàu, đặc biệt là dùng napa để chỉnh trơn tuyến hình rất dễ, nghe mấy bác ở ngoài viện thiết kế đã dùng thì việc chỉnh trơn rất đơn giản, không có phứt tạp như autoship, bác nào trong 4rum đã dùng qua, có thể share cho anh em một vài thông tin ko. Phần mềm này hiện nay nó bán 1,5 tỷ đồng. Bác nào có soft thì share anh em với nhé
In the early design stages, it’s
vital to obtain reliable and accurate information quickly. It’s also
essential that extensive design changes to the geometry model can be
made swiftly and easily, as needed. With NAPA you can quickly and
easily model surfaces and compartments into 3D, perform relevant
detailed analysis, make changes and re-evaluate the design to ensure
that it is technically feasible and satisfies the requirements of the
nature, the ship owner, the shipyard and the authorities.
The
NAPA system contains all of the functions necessary for the contract
design of ships so that the optimum design solution is obtained before
the contract is signed. Some examples of the many functions included
are:
- Hull form design
- Compartments and internal geometry
- General arrangement
- Speed and power prediction
- Hydrostatics and stability
- Damage stability
- Loading conditions and intact stability studies
- Longitudinal strength
- Weight and cost estimation
- Required freight rate studies
- Tank calibration and capacity tables
- Freeboard and tonnage calculation
- General purpose optimization tools
- Drawings and documentation
Contract Design Made Easy with the Contract Design Manager
The
Contract Design Manager application is intended for quick and easy
creation of the whole 3D product model with NAPA at an early design
stage. The Manager provides a logical workflow for contract design. The
3D product model created serves as the primary source of precise design
information at stages leading up to the contract.The Manager
works as a user-oriented, visual interface for NAPA and manages the
extensive design processes. Changes, adjustments and updates can be
carried out easily with the Manager. All tasks, their relative order,
up-to-date status and dependencies can be seen at a glance. Relevant
detailed analyses can be performed and the feasibility of the design
can be re-evaluated effortlessly, making the application ideal for the
early design stages.
Advantages
The
key benefit of the NAPA system is the unequalled speed at which design
variations can be investigated and the final design accomplished. NAPA
offers an integrated package with the wide variety of applications
needed in ship design. The outcome of the early design with NAPA can be
further developed in the latter stages of design, including meeting the
final challenges of delivery and operationHydrodynamic Design and Analysis
Integrated performance prediction routines facilitate the evaluation of the hull design quickly in the early design stage.
- Power prediction, including model and full scale reference data.
- Seakeeping analysis, 6. d.o.f. response in irregular waves, seakeeping criteria, downtime.
- Manoeuvring simulations according to IMO resolution A.751(18).
- Station keeping and other special studies.
Hull Form Optimization and CFD Analysis
More detailed hull design evaluation and optimization based on CFD is available entirely within the NAPA system.
- Wave resistance according to an integrated CFD method.
- Panel model generation and transfer to external advanced CFD systems.
- Multi-objective genetic algorithms to handle any kind of optimization problem.
Optimization,
parametric definitions and the hydrodynamics subsystems make NAPA one
of the only, if not the only, system which integrates all of the tools
necessary for hydrodynamic design of the hull surface.
