▲ End goal: eliminate all manual meshing

▲ Today: some hand-editing required after

batch meshing

▲ Today: significant reductions in time and

labor to complete meshes

▲ Distribute meshing jobs using PS/Pro

▲ Check meshes back into PDM and EDM

ADM Federation Web Application Architecture

Use ADM web services

Use common object model implemented by each ADM sub-system

Leverage ADM web portal for granular data query and view

ADM Roadmap: Enable Extreme Scalability

Requirement: Ability to support companies of any size

Deploy current ADM at smaller companies

Divide large installations into multiple sub-domains

Deploy ADM systems for each sub-domain

Federate ADM sub-systems using a standard Web Architecture

Data Sources

• Process Data

– est practice documents – Regulatory requirements

• Imported data files

– CAD Geometry – From PDM System Vaults or shared drives

– FE Meshes – From other analysis projects, from shared drives…

– Load Curves – From physical tests – oundary Condition definitions – From process documents

– Material Properties – From Materials Databases

– ard point locations and surfaces – From CAD data

• Other Data

– A ill of Materials from PDM

• Most of this data is available in electronic form

• This data could be located on a variety of physical systems:

– PDM Systems and Enterprise databases

– Local and Shared Drives

– FTP and Web servers

8/8/2019 2-a_altair


Considerations

• Computing Infrastructure

– Load balance web application servers

– Support solver execution load balancing systems

• Distributed Locations

– Develop federation schema to provide

Crisp performance for small CAE teams

Only required validation metrics information to the enterprise

• Network Bandwidth

– Minimize network traffic

Perform batch saves

Minimize continuous server hits

• Archival Systems

– Support off-line storage

• Shared Drives

– Avoid vaulting large result files

A Case Study

ADM was selected to mange Pratt’s Engine Test Data

Unique Requirements Very large raw test data files cannot be moved from the NAS

Custom GUI suitable for Pratt’s test data users

Automatic Test creation when tests are uploaded to NAS

Post-processing support with their existing applications

Implementation will be done in 3 phases

Phase 1 – Meta-data configuration and System install

Phase 2 – Test data monitoring and Test creation agent

Phase 3 – Post processing support

Not a major HW customer
