An Automated,  Complete Simulation Preparation Solution

STRIVING FOR A PROCESS THAT WORKS

Since its introduction, PowerDELTA® has helped leading companies gain an advantage with better performing products, reduced costs, and accelerated time-to-market by frontloading

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.

 

PowerDELTA with integrated PowerCLAY® morphing technology further streamlines the simulation preparation process. This latest release of PowerDELTA enables automation of simulation preparation for rapid creation of design alternatives for design space exploration.

 

Typical challenges in the simulation preparation process:

    • Long mesh baseline preparation time

    • Difficult to quickly create design alternatives for iterative testing

• Poor quality design/early-stage data

    • Redundant simulation model builds

    • Responding rapidly to design changes

    • Capturing & reusing best practices

 

 

PowerDELTA 2.1 includes PowerCLAY real-time morphing functionality to streamline model preparation and optimization runs.

 

 

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. This is further complicated by the need to handle conceptual geometry and poor quality carry-over CAD data.

 

Exa Corporation, known for its innovative products that enable real-world engineering processes to become more efficient, offers PowerDELTA to streamline and automate the simulation model preparation process. PowerDELTA applies proven concepts of parametric feature modeling, direct mesh morphing 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.

CAPABILITIES OVERVIEW

PowerDELTA with PowerCLAY simplifies and streamlines the laborious and time consuming process of model preparation and model modification. Some unique features illustrated below:

 

 

CREATING DESIGN ALTERNATIVES WITH PowerDELTA:

Patented, real time studio-quality lattice morphing

The patented lattice morphing capability, previously only available in PowerCLAY, has been implemented in PowerDELTA. With lattice morphing, individual lattice points give precise control of the surface shape without having to introduce additional constraints. Various controls ensure smooth transitions between morphed regions and the original surface. The resulting surfaces are at a quality level expected by the design studio, resulting in a higher likelihood that the modified designs may be acceptable to the studio. Each lattice is a feature on PowerDELTA’s history-based feature tree and so can be modified at any time and can be included in standard, reusable, meshing templates that dramatically streamline the meshing process. PowerDELTA with PowerCLAY morphing can now manage the whole design space.

 

Interactive, 3D Morphing

With the patented lattice morphing capability, creating design alternatives is easier than ever. Morph surfaces real-time for rapid and precise shape change.

 

Multi Lattice Management

Multiple overlapping morphs can be applied to the same region, without worrying about interaction between morphs. The system takes the care of combining the effect of all morphs together

 

Axis Symmetric Morph

Specialized cylindrical lattice morphing maintains axis symmetry, speeds up the process of modifying fans and wheels.

 

Design Space Management

The design space can include morphs, translate or rotate operations and part variants. Easily manage the design space from a single table.

 

Assisted Lattice Creation

Morphing long, narrow features such as an A-pillar section, are often a bottleneck to the design alternative creation process. PowerDELTA’s sweep lattice dramatically cuts the time for morphing these types of complex curved shapes
