In this presentation, I was trying to solve coupled thermo-mechanical finite element analysis for design of blast furnace using some software. It was done through some automatic technique, which falls under the broad umbrella of “Design Automation”.

2. Design Automation
 Pre computer (Standardization)
Grouping, Analysis, Design, Drawing
 Excel (VBA)
 HPC
 Engineering Software
 Modelling: Analysis, Design, Drawing
Cloud: Security, Privacy, Interoperable
 Parametric Modelling
Interoperable
 In-house DA Framework
 API

3. Blast Furnace
Liquid Iron From Ore
Counter current Gas-Solid
/ Liquid reactor.
High temperatures and
pressures.
Solids charged from top
Reducing gases generated
at the bottom by
combustion of Carbon

16. BIM
Building Information Modelling is a very broad term
that describes the process of creating a digital model of a
building or other facility (such as a bridge, highway,
tunnel and so on)
 Level 0: Unmanaged CAD
 Level 1: Managed 2D, 3D CAD
 Level 2: Managed 3D Environment
 Data Attached
 Separate Discipline Models
 Level 3: Single, Online, Project Model
 Construction Sequencing,
 Cost and Lifecycle Management Information
