AgendaAn introduction to workflows and automationA brief discussion of processes used in design analysis, and some of the tools that can be usedSIMULIA workflow exampleIllustrating different processes that can be automated, and how they vary in complexity and implementationConcluding remarksHow you can get started and how we can help
Opening remarksWhat is a workflow?One or more analytical activities that follow a set of rules
A process that changes information from one form to another
A method by which a physical phenomenon can be understood
Why automate workflows?Eliminate tedious repetitive tasks
Reduce the chances of human error
Make validation easier
Enable computation of complex algorithms
