1) Introduction„Efficient usage of CAE“ … the initial idea behind SimScale.
● Easily accessible
● Flexible and scalable
● Simple to use
CAE should be ...

A new approach to CAE:
● Browser-based interface
● Generic CAE environment
● Connected to computing centers

2) The platform
User Frontend Web Server CAE Backend
The infrastructure: A distributed hardware and software system.
● No special HW / SW requirements
● Reliable internetaccess
● Browser-based● General data
management, storage & backup
● On-demand compu-ting power
● Different IaaS prov-iders available

2) The platformThe architecture: A generic CAE environment
Collaboration Simulation setup
User interaction 3rd-party solver
● Simulation / Projectsharing remotely
● Colleagues, Clients
● Meta layer describesthe type of analysis
● Solver agnostic
● 3D Rendering● Intpretation of the
meta layer
● Actual computing. Currently:OpenFOAM / CalculiX /Code_Aster / SU2 / Gerris /FEniCS / ...

4) CAE and „the Cloud“The status of cloud-based CAE today
Technical implementations:
● Local desktop client, remote computation● Remote-desktop interaction● Browser-based interaction
Pricing models:
● „Bring your own license“ (BYOL)● Pre-paid simulation contingent● On-demand usage („pay-as-you-go“)
Cloud-based CAE today
Basic Advantages:
● Scalability● Flexibility
Challenges:
● Data traffic● Internet dependency● Performance reduction through virtualization● „Cloud-Image“ problem
The Cloud discussion in a nutshell

4) Why is that efficient?Porting CAE to the browser brings some native advantages.
Flexible
Simple to use
Open
Scalable
Collaborative
