CSI ETABS 2016 v16.2.0 build 1645 x86+x64
The innovative and revolutionary new ETABS is the ultimate integrated software package for the structural analysis and design of buildings. Incorporating 40 years of continuous research and development, this latest ETABS offers unmatched 3D object based modeling and visualization tools, blazingly fast linear and nonlinear analytical power, sophisticated and comprehensive design capabilities for a wide-range of materials, and insightful graphic displays, reports, and schematic drawings that allow users to quickly and easily decipher and understand analysis and design results.
From the start of design conception through the production of schematic drawings, ETABS integrates every aspect of the engineering design process. Creation of models has never been easier - intuitive drawing commands allow for the rapid generation of floor and elevation framing. CAD drawings can be converted directly into ETABS models or used as templates onto which ETABS objects may be overlaid. The state-of-the-art SAPFire 64-bit solver allows extremely large and complex models to be rapidly analyzed, and supports nonlinear modeling techniques such as construction sequencing and time effects (e.g., creep and shrinkage). Design of steel and concrete frames (with automated optimization), composite beams, composite columns, steel joists, and concrete and masonry shear walls is included, as is the capacity check for steel connections and base plates. Models may be realistically rendered, and all results can be shown directly on the structure. Comprehensive and customizable reports are available for all analysis and design output, and schematic construction drawings of framing plans, schedules, details, and cross-sections may be generated for concrete and steel structures.
ETABS provides an unequaled suite of tools for structural engineers designing buildings, whether they are working on one-story industrial structures or the tallest commercial high-rises. Immensely capable, yet easy-to-use, has been the hallmark of ETABS since its introduction decades ago, and this latest release continues that tradition by providing engineers with the technologically-advanced, yet intuitive, software they require to be their most productive.

Lindo What'sBest! v15.0.1.0
What'sBest! is an add-in to Excel that allows you to build large scale optimization models in a free form layout within a spreadsheet. What'sBest! combines the proven power of Linear, Nonlinear (convex and nonconvex/Global), Quadratic, Quadratically Constrained, Second Order Cone, Semi-Definite, Stochastic, and Integer optimization with Microsoft Excel -- the most popular and flexible business modeling environment in use today. The recently released What'sBest! 15.0 includes a number of significant enhancements and new features.
Enhancements to the Simplex solvers boost performance on linear models. Large models solve an average of 20% faster using primal simplex and 15% faster for dual simplex.
New symmetry detection capabilities dramatically reduce the time required to prove optimality on certain classes of models with integer variables. Performance has been improved on Markowitz portfolio problems with minimum buy quantities, and/or limit on number of instruments at nonzero level. Other enhancements provide faster solutions on certain task assignment-like models.
Stability and robustness of the Global solver has been improved through several enhancements to quadratic recognition and range reduction. Improved exploitation of convexity of certain ratio constraints, e.g., as found in heat exchanger network design problems.
Several new functions and constraint types are recognized, e.g., the =WBALLDIFF() All Different constraint, for general integer variables. The =WBALLDIFF() function allows one to specify a set of integer variables, such that each variable in the set must have a unique value, different from all other variables in the set. |

Spider Financial NumXL v1.65.42892.1
NumXL is a suite of time series Excel add-ins. It transforms your Microsoft Excel application into a first-class time series software and econometric tool, offering the kind of statistical accuracy offered by the far more expensive statistical packages. NumXL integrates natively with Excel, adding scores of econometric functions, a rich set of shortcuts, and intuitive user interfaces to guide you through the entire process. Whether you have a simple homework problem or a large-scale business project, NumXL simplifies your efforts. It helps you reach your goal in the quickest, most thorough way possible. NumXL keeps your data and results connected in Excel, letting you trace your calculations, add new data points or update an existing analysis, easily sharing your result with co-workers - and, yes, even with your boss. The learning curve couldn't be easier: NumXL requires no programming or scripting. You will not have to move your data between any external programs. You can also do any kind of ad-hoc analysis, as all of NumXL functions are accessible in your spreadsheet, and inside VBA environment should you choose to script.

DotSoft ToolPac v17.0.3.6
In the never ending quest for faster AutoCAD/BricsCAD systems, users go the extra mile to purchase the fastest hardware. Faster processors, graphics cards, etc., are implemented in an attempt to speed up the processing of drawings. These improvements come at great expense and only provide a marginal gain in the amount of time it takes to actually complete a drawing. This expensive hardware is often underutilized as the operator wastes time doing repetitive tasks in the struggle to finalize a drawing.
If you do only one upgrade to your system this year, it should be the implementation of productivity software. Our ToolPac product was designed to eliminate the numerous bottlenecks in AutoCAD and BricsCAD. It contains over 750 functions designed with one purpose in mind, to save you time.
ToolPac is in use today by thousands of architects, engineers, and designers! This comprehensive collection of productivity tools works with AutoCAD 2007 or higher (LT not supported) or BricsCAD v12 Pro or higher. It works equally well in all environments, including Architectural, Engineering, Civil, Mechanical and Design.
