SACS 5.6 Update

BigCrab · 17/11/15

Em có nhận được email của Bentley thông báo 2 tuần rồi nhưng bận quá chưa thông báo ngay cho các bác biết được. Em đã dùng thử và chưa thấy có gì mới so với các phiên bản 5.5, 5.4 và so với phiên bản 5.3 SP1 mà anh em mình vẫn dùng thường ngày. Các bác tìm dùng và chia sẻ kinh nghiệm nhé!

Dear SACS User,
Welcome to Bentley’s Offshore Structures eNewsletter. Our goal is to keep you informed of current capabilities and future development relating to the Bentley SACS analysis and design software.
Regards,
SACS Product Team,
Bentley Systems
The latest release of SACS – version 5.6 – is now available. SACS v5.6 contains numerous major enhancements across the range of modeling, analysis, and design functions.
Some of the areas of enhancement include the following and are described in detail below:

New Hull Mesher

Updated EC3 and NORSOK Design Codes

Upgraded Wind Turbine Analysis

Automated Non-Tubular Joint Meshing

New Liquefaction Capability

ProjectWise Integration

Trust Licensing

New SACS v5.6 Hull Mesher

Our newest addition to the SACS family of applications is Hull Mesher. A part of the SACS Marine Enterprise suite, Hull Mesher provides a range of structural modeling tools optimized for creating stiffened plate structures, such as those found in the hulls of floating vessels and structures. As such, it is very complementary to the jacket and topsides modeling functions in Precede.
Hull Mesher creates a standard SACS sacinp model input file and provides commands for importing dwg and dxf geometry; sketching and generating members; and sketching plate panels. It also includes some smart commands for automatically generating panels on the imported geometry including patches with arbitrary geometries and interior holes. To support stiffened panels, Hull Mesher provides a range of tools for generating stiffeners across a panel, generating stiffening flanges around openings, and offsetting stiffeners to the panel. In this first release, Hull Mesher can comfortably deal with models containing 100,000 or more plate elements. Future releases will support even larger models.
Hull Mesher is ideal for stiffened plate structures
EC3 and NORSOK 2013 Code Update

In every release of SACS, Bentley enhances design code checking capabilities. SACS v5.6 contains additional section shapes (including unsymmetrical plate girders) to the EC3 steel code check and added support for the recently released NORSOK 2013 code. This Norwegian code update includes revised checks for joint cans and member design.
Wind Turbine Updates

The United States National Energy Research Laboratory (NERL) is a major research center for all forms of energy technology—including wind power. One of the results of their research programs is the FAST solver, which predicts performance and efficiency of wind turbines and their associated structure. When the support structure is more complex (for example, the jacket structures required for offshore turbine arrays in deeper waters), SACS is an ideal tool to be used in combination with FAST.
In SACS v5.5, Bentley added a coupled solution so that the standard FAST program could be run in conjunction with SACS to produce the aerodynamic loads on the tower. Within SACS v5.6, Bentley has again updated FAST integration. Now included is the option of a non-integrated, fully coupled solution, which allows SACS users to customize the FAST program to suit their particular needs, but still use it in combination with SACS.
Non-Tubular Joint Meshing and More

For some time, SACS has been capable of automated meshing of tubular joints in order to more accurately model joint stiffness and/or determine stress concentration factors for fatigue. A significant enhancement in SACS v5.6 is the ability to automatically mesh non-tubular joints. This is particularly useful for topside joints where the combination of tubulars with non-tubulars, or joints with intersecting flanged section shapes, can make calculating stress concentration factors difficult.
The new capabilities offer a completely automated way to mesh these joints, along with the ability to specify the mesh density within the joint. As with tubular joint meshing, the meshed ends of the connecting members are connected to the beam elements along the remainder of the member using automatically created rigid offsets. This ensures full moment continuity from the meshed joint to the remainder of the structure.
Other meshing enhancements in the SACS v5.6 release include the ability to automatically mesh around ring stiffeners on members and also automatically re-mesh plates on topsides decks.
Liquefaction Effects

In seismic activity zones, the effect of liquefaction on soils is well known and results in a significant reduction in soil stiffness. To model this behavior and more accurately predict pile and structure response, Bentley has added new liquefaction effects to SACS v5.6. Upgrading the PSI, Collapse, and Pile3D modules, the new capability allows the entry of earthquake magnitude and peak ground acceleration. From there, users can define a series of soil strata—each having a defined soil type and position relative to any water table and measured soil properties.
ProjectWise Integration

ProjectWise is Bentley’s collaboration system for engineering teams. It allows all project team stakeholders to share documents across multiple sites with the confidence that they have the latest version of each document and that their changes will automatically replicate efficiently and reliably to other sites.
When using SACS v5.6, users will notice a new ProjectWise sub-menu in the SACS menu of Precede and Datagen. The commands in this menu allow users to check in/out SACS model files to/from a ProjectWise repository. This is the first step in a major integration between SACS and ProjectWise. Future releases will support complete synchronization of SACS project directories and the corresponding project folders in ProjectWise.
Trust Licensing

The SACS v5.6 release includes an evolution of the licensing system to Bentley’s trust Licensing. This replaces the previous IEG licensing system used by SACS. This licensing model, already available in Bentley’s other desktop products, does not restrict the number of licenses that subscribers can use, avoiding the need to halt production while waiting to purchase new licenses.
With trust licensing, subscribers also benefit from license pooling, which allows users within a team to maximize their software utilization by centralizing and sharing licenses across all sites within a country. Unlike concurrent licensing, license pooling supports offline disconnected use which makes licensing more reliable. The license usage is tracked in one-hour intervals. You can use the SELECTserver web management interface to analyze organization-wide software usage including what, when, where, and by whom licenses are being used in order to make informed decisions about your organizations’ license needs.
Under trust licensing, the license management pane within the Executive is no longer required and has been removed as licenses are no longer checked out and checked in. If you do manually checkout licenses – which is only required for offline usage of more than 30 days – then you can use the License Tool, available from the Interactive Programs tab, to review available licenses and the status of any license checkouts.

Mình muốn hỏi ae trên diễn đàn đã ai trực tiếp dùng SACS 5.6 để giải quyết mấy bài toán mà bản 5.3 chưa làm được thì chia sẻ nhận xét chút? Các tool thì nhà sản xuất phần mềm nhiều khi cứ vẽ đại ra cho hoành tráng thôi chứ cũng phải thử sử dụng nó thì mới phán được là nó hoạt động chi tiết tới đâu, giải quyết được gì và ưu khuyết điểm ra làm sao.
(Ở một topic khác thì bác Bigcrab cũng đã gửi cái datasheet cho bản 5.6 để ae chiêm ngưỡng)

Sao bác không tự trực tiếp dùng thử và cảm nhận em nó đi, thấy bác còn dùng cả STAAD.Offshore rồi cơ mà :-?

Dạ em cũng chẳng phải là chuyên gia chuyên về software này nọ lên cũng không dám nói là biết hết cái này tới cái kia, về mấy cái tool thì cái gì đã từng trực tiếp sử dụng, trực tiếp làm rồi thì em nói là em biết thôi.
Cách đây mấy tháng em cũng nghe nói là SACS 5.6 mới ra và có cải tiến nhiều thứ, tuy nhiên em chưa có thời gian để cài và chạy thử cái bản 5.6 xem nó ra làm sao nên mới hỏi trước ae đã cài và dùng rồi, nếu không có gì đột phá thì cứ chơi với 5.3 cho rồi. Về cái món staad.offshore thì cũng vậy.
