AgendaA web-application enabling a new approach to CAE.

1) Introduction

2) The platform

3) Hands-on 1: Structural Mechanics

4) Concept and design

5) Hands-on 2: Fluid Dynamics

6) Discussion

7) Wrap up: Why is that efficient?


1) Introduction„Efficient usage of CAE“ … the initial idea behind SimScale.

● Easily accessible

● Flexible and scalable

● Simple to use

CAE should be ...


2) The platformBrowser-based, cloud-connected. No local hardware or software.

Fig.2: Result visualization of anaerodynamics simulation

A new approach to CAE:

● Browser-based interface

● Generic CAE environment

● Connected to computing centers


3) Hands-on 1: Structural mechanicsVideo demonstration of a FEM simulation

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

Fig.: Impressions of the SimScale platform

Worldwide access, one platform

Interactive project sharing, community features

Straightforward integration of new solvers / meshers

Simulation templates, library, zero-client installation

On-demand hardware, elastic IT infrastructure.


4) FunctionalityA generic CAE environment providing access to different solvers.

● A browser-based CAE interface is possible

● Modern web-technologies enable new approaches in CAE

● Transforming a desktop application to an online-platform advances accessibility and scalability of CAE

● HPC resources on demand become cheaper and easier to access

● The future of CAE stays intereresting
