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.

POWERDELTA HIGHLIGHTS:

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.

 

Rapid, 3D, part sorting and organizing

The full capabilities of PowerDELTA’s multiple viewers, multiple branches, and drag and drop geometry instancing have now been coordinated to provide a simple to use part sorting process that allows a user to confidently sort thousands of imported parts and assemblies in minutes. The end results are the necessary part groups (branches) that feed directly into PowerDELTA’s automated meshing templates. Initial mesh model creation has never been this fast or this straight forward.

 

Interactive part manipulation (translate/rotate/delete)

Whether CAD parts are provided in the as manufactured position instead of as assembled or sub-assemblies are delivered in a different coordinate system, those who work with production assemblies know there are always small orientation issues to be corrected. To address this, PowerDELTA includes the ability to translate and rotate geometry into position and delete some geometry details during the sorting and cleanup process.

 

Local Remesh: Fix even the most challenging mesh areas

Even with all the smarts built in PowerDELTA’s wrap, mesh union, remesh, and autofix features there can still be local areas of the mesh that need some fixing. A new capability for Local Remesh allows the user to select a subset of the mesh to be remeshed according to desired criteria while maintaining all critical geometric details. This allows even the most challenging mesh preparation models to be completed entirely with PowerDELTA.

 

Prepare meshes according to fidelity required

Powerful new lattice creation techniques to adaptively fit lattices to the mesh geometry for fast preparation to prepare components into a single, large simulation-ready mesh.

 

Improved retention of partition boundary definition

One of the hallmarks of the highly successful PowerDELTA wrapping feature is the ability to preserve the details of sharp corner detail from the original geometry. Recent releases have further improved this capability to ensure that the final wrapped mesh contains all of the important partition boundaries from the original model even if they were not defined by a sharp edge. After wrapping with PowerDELTA, it is difficult to tell the simulation mesh from the original geometry.

 

Automatic removal of holes defined in CAD parts

PowerDELTA now provides the capability to remove arbitrary shaped holes directly from the CAD model definition resulting in cleaner more precise detail removal and subsequently simpler and faster meshing process. “Inner loops” of CAD surfaces are removed retaining the underlying geometric surface definition.

 

Leverage partition information to automate meshing

Partition information is very powerful for organizing and automating a standardized meshing processes. A well partitioned model can automatically establish the meshing actions to be applied at each stage of the meshing process. PowerDELTA increases the effectiveness of this functionality by automatically making partitions available inside features as groups used to refine and control meshing parameters on specific parts of the model. So more than ever PowerDELTA supports reusable mesh templates that allow meshing practices to be captured in the features themselves and re-played automatically.
