PowerDELTA with PowerCLAY

POWERDELTA 2.4 (INCLUDING POWERCLAY)

Exa's PowerDELTA with PowerCLAY streamlines and automates 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. Design data in most major CAD and mesh formats are supported.

Since its introduction, PowerDELTA has helped leading companies gain an advantage with better-performing products, reduced costs and accelerated time-to-market by front-loading product performance analysis in the design process.

TYPICAL CHALLENGES IN THE SIMULATION PREPARATION PROCESS:

  • Poor quality design/early-stage data
  • Long manual mesh baseline preparation time
  • Capturing and reusing best practices
  • Difficult to quickly create design alternatives for iterative testing

EFFICIENT SIMULATION ANALYSIS RELIES ON MODEL PREPARATION

A key activity within the analysis process is preparing models for simulation, and in most organizations, of which is a significant barrier to an efficient design process. Typically, mesh preparation time is extremely long — taking many days or even weeks. PowerDELTA reduced this turn-around time when starting from high-quality clean CAD – typically native CAD formats.

CREATING HIGH-QUALITY FLOW CRITICAL MESHES

All surface meshes needed to be prepared for applications such as external aerodynamics or external wind noise can be prepared completely using PowerDELTA. These meshes are commonly described as “flow-critical” or “Class-A” (for which the underlying CAD model must be “clean”). PowerDELTA provides CAD editing and meshing operations to assist users in preparing these types of meshes entirely in PowerDELTA.

 

Interactive, CAD Editing
Surface and wire creation features and automated functions that can consolidate large sets of CAD data into one connected CAD geometry help in preparing simulation ready geometry.

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 can be modified at any time and included in standard, reusable meshing templates that dramatically streamline the meshing process. PowerDELTA with PowerCLAY morphing can now manage the whole simulation design space.

Interactive, 3D Morphing
With the patented lattice morphing capability, creating design alternatives is easier than ever. Morph surfaces in real-time for rapid and precise shape changes.

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

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

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