6. Simulation Based Product Design
• Simulation is considered third pillar of Science &
Technology
• Simulations has No Cost constraints, harsh/unrealistic
parameter range, EHS concerns.
• Development in mathematical models, computing
resources
• Reliable, efficient and affordability is the key driver for
Concurrent Product Development and growth

8. Multiscale Modeling
Multi scale modeling Framework
• Multiscale model is a
mathematical model
formed by combining
partial model at different
length and time scales.
• Efficient linking is critical
• Away from predicting
known properties towards
new materials with novel
properties.
