PowerDELTA Streamlines & Accelerates Your Simulation Model Preparation Process

 

STRIVING FOR A PROCESS THAT WORKS

In today’s ultra-competitive marketplace the only way to achieve breakthrough product development is to change the product development process. Leading companies are gaining the advantage with better performing products, reduced costs, and accelerated time-to-market by front-loading product performance analysis in the design process where critical and costly design decisions are made. A rapid and accurate analysis process becomes critical when front-loading, since many more design variations need to be analyzed compared with traditional late-stage design verification analysis.

 

Typical challenges in the simulation preparation process:

    • Long mesh preparation time

    • Poor quality design/early-stage data

    • Redundant simulation model builds

    • Responding to design changes

    • Capturing & reusing best practices

 

 

EFFICIENT ANALYSIS RELIES ON SIMULATION MODEL PREPARATION

A key activity within the analysis process is preparing models for simulation and in most organizations it’s a significant barrier to an efficient process. Typically, mesh preparation time is very long – taking many days or even weeks – and is complicated by the need to handle conceptual geometry and poor quality carry-over CAD data. Sorting and organizing the hundreds of design parts needed for analysis is manual. Most companies build redundant simulation models for different types of analysis. Worse still, simulation models are usually one-time, one-use only due to the extreme difficulty traditional tools have updating the model when the design changes.

PowerDELTA streamlines your model preparation process from CAD to simulation-ready so you may simulate, evaluate and optimize your designs faster. Click here for larger version of this workflow diagram to show a the new, faster way to prepare your models for simulation.

 

 

Exa Corporation, known for its innovative products that enable real-world engineering processes to become more efficient, has developed PowerDELTA® to streamline and automate the simulation model preparation process. PowerDELTA applies proven concepts of parametric feature modeling and history tree model management to the process of simulation model creation and update. Design data in most major CAD and mesh formats are supported—even at varying levels of quality. PowerDELTA enables team collaboration and change on any level. Without PowerDELTA, only a fraction of the simulations needed to evaluate and optimize a product early in the design cycle can actually be run.
