Introducing More: Simulias Extended Token Licensing https://www.cati.com/blog/introducing-more-simulias-extended-token-licensing/ https://www.cati.com/blog/introducing-more-simulias-extended-token-licensing/#respond Tue, 26 Aug 2014 02:09:00 +0000 https://live-cati-marketing.pantheonsite.io/introducing-more-simulias-extended-token-licensing/ Dassault Systemes is continuing to expand its Simulia realistic multi-physics simulation technology portfolio through acquisition of 3rd party software. With this expansion comes added value for customers who are already using Simulia products and are interested in additional capabilities of other software beyond best-in-class ABAQUS capabilities.

Companies who currently use ABAQUS know that with Simulia’s Extended Tokens licensing, they already have 3-in-1 access to the Simulia products Abaqus, Tosca and Isight. With the acquisition of Safe Technology’s fe-safe, Dassault Systemes added one more code to the Extended Token product line, making it a 4-in-1 powerhouse. Abaqus 6.14 was released on July 25th 2014, incorporating fe-safe into the Extended Token bundle. While the portfolio continues to evolve and becomes even more impressive, the pricing remains the same. This extended catalog of products allows businesses to expand their CAE capabilities at no additional charge. For the price of one great piece of software, users now has access to:

ABAQUSAbaqus: The first Simulia product suite, ABAQUS provides comprehensive solutions for challenging engineering problems, reducing costs and inefficiencies; consolidating tools and processes; and gaining competitive advantage. ABAQUS comes with an interactive user interface for creating models, an implicit solver, an explicit solver, and a CFD solver. Its contact and nonlinear materials and analyses capabilities are second to none, and it efficiently manages large model assemblies and allows for parallel processing. Significant performance gains are possible because ABAQUS scales well for multicore, multi GPU, HPC processing.

IsightIsight: Isight enables engineers to automate design exploration and perform parametric optimization. Isight increases efficiency, accelerates product design, and reduces manual errors. Isight continues to provide designers, engineers, and researchers an open system for integrating design and simulation models to automate the execution of hundreds or thousands of simulations. Isight enables time saving and product improvement by optimizing against performance or cost metrics through statistical methods, such as design of experiments (DoE) or Design for Six Sigma (DoSS). Dassault Systemes introduced Extended Token licensing in July, 2012. The initial release of Extended Token licensing included access to ABAQUS and Isight using a common token pool.

ToscaTosca: In November 2013 Dassault Systemes expanded Extended Token licensing by including Tosca, an optimization suite consisting of Tosca Structure and Tosca Fluid. Tosca enables engineers to take complete advantage of any improvement potential while leveraging advanced simulation capabilities. Tosca creates optimized design concepts to achieve the highest performance, quality, and light weighting in an abbreviated development time.

  • Tosca Structure includes optimization for topology, shape, sizing, bead, and morph
  • Tosca Fluid addresses the design and optimization of fluid flow systems

fe-safefe-safe: In July 2014 Extended Token licensing was again expanded, this time with fe-safe. Fe-safe is a durability analysis software designed for fatigue analysis of finite element models. Fe-safe is fast, accurate, and easy to use. It fits smoothly into the design process, enabling users to develop products that are designed for durability. Fe-safe is used for:

  • estimating warranty claims curves based on probabilities of failure
  • producing contour plots to reveal fatigue life and crack sites
  • identifying non-critical loads at significant points on a model in order to design physical tests using fewer loads and fewer actuators

Dassault Systemes recently acquired SIMPACK. SIMPACK is a general purpose, multi-body dynamics simulation software used for the dynamic analysis of any mechanical or mechatronic system. It enables engineers to generate and solve virtual 3D models in order to predict and visualize motion, coupling forces, and stresses.

Currently SIMPACK is not part of Simulia’s Extended Token licensing. However, SIMPACK will soon be available to purchase as a stand-alone product. It’s never been a better time for great value on powerful engineering software.

How TOSCA Optimization Software Can Improve Your Product Development Process https://www.cati.com/blog/how-tosca-optimization-software-can-improve-your-product-development-process/ https://www.cati.com/blog/how-tosca-optimization-software-can-improve-your-product-development-process/#respond Wed, 23 Apr 2014 01:52:00 +0000 https://live-cati-marketing.pantheonsite.io/how-tosca-optimization-software-can-improve-your-product-development-process/ TOSCAPreviously, we discussed the importance of selecting the right VAR for providing you with SIMULIA brand products, such as Abaqus, in order to develop products faster and at lower cost. If you are interested in further reducing costs, getting products to market faster, and potentially lowering your warranty liability, consider using Dassault Systemes’ topology optimization software, TOSCA.

Product development the “old-fashioned way” is done through a process of building, testing, evaluating and redesigning, and then repeating those 4 steps over and over – until the product looks and performs adequately. This method can be very time consuming and expensive, which is why simulation software such as Abaqus was developed. Engineers using Abaqus are able to simulate performance virtually, and do not have to build and test as many prototypes, saving time and money.

Topology optimization software further accelerates the product development cycle by producing an optimized design the first time, based on the given design space, objectives and constraints. Tosca begins with the maximum allowable design space, runs a FEA simulation for stress or fatigue to determine the weak points of a design, then “removes” extraneous material. Next, TOSCA repeats this process until the objectives (for example, 50% reduction of volume) and constraints (for example, manufacturing constraint for castings) have been met. The resulting geometry is a design proposal for an optimized design.

TOSCA optimization software reduces development time and costs more so than traditional CAE software alone by automating and accelerating the design-simulate-evaluate loop. Engineers utilizing it then must build only one or even no prototypes, automatically shortening the product design process and eliminating significant costs.

As a designed driver of Abaqus, Tosca has a number of advantages. Tosca is an open system and seamlessly integrates with leading FEA solvers and exports design results to CAD systems with Splines or STL data. Its engineering benefits include:

  • Increasing a design’s durability
  • Increasing its natural frequencies
  • Reducing material and weight/minimizing mass
  • Reducing stress concentration

SIMULIA TOSCASIMULIA’s TOSCA product offers both structural and fluid engineering capabilities. TOSCA Structural accomplishes linear and nonlinear structural optimization for stress, durability, NVH, as well as for topology, shape, bead, sizing, and morphing.

Specifically, some of the benefits of TOSCA Structural include:

    • Bead optimization for increased stiffness and reduced vibration noise: adding ribs or extending sheet metal to improve the static and dynamic properties of sheet metal shell structures.
    • Shape optimization for homogenized stress by automatic modification of the surface geometry.
    • Sizing optimization of complex shell element structures for stiffness or dynamics.

TOSCA fluidTOSCA Fluid optimizes for reduced pressure drop and improved flow uniformity, in order to improve flow efficiency. A single CFD solver run is sufficient for optimization in TOSCA Fluid.

If you would like to learn more about how TOSCA or other Simulia-brand products can help your business lower its costs and get products to market faster, please contact CATI.
