1. Numerical simulation
Basics
Review and Refreshment

2. Experimsntal, Theoretical or analytical
Analysis
●Theory is based on assumptions, postulations and laws of actions
●In physics, chemistry and other science subjects, many theorems
are studied and mathematics helps in quantification and
understanding
●These theorems are presented in terms of independent and
dependent parameters
●Analytical analysis helps to provide physical dependency of
parameters butit difficult to solve complex real world
problem example: weather prediction, flows of rives,
testing of large airships etc.

3. Methods of Analysis
Artificial intelligence
Supports Simulation and
decision making process

4. Modeling and Simulation
●Modeling and simulation is a technique to
prediction the science and explore new
knowledge.
●It is useful to solve real world problems which can
not be solved bytheory and may be expensive
by experimental analysis

5. ●Computational fluid dynamics
(CFD)is a technique of modeling
and simulation based on numerical
modeling for fluid flow.
●Using the CFD technique, heat and
mass transfer, reactive flow, multi-
phase flow and combustioncan be
analyzed via various numerical
models.
Computational Fluid Dynamics CFD

6. Computational Fluid Dynamics CFD

7. ●FEA is a technique used to solve structure problems
●Explicit dynamics to find stresses and deflections
Finite Element Analysis (FEA)

8. Finite Element Analysis (FEA)

9. Modelings and Simulation is knownas a third pillar of
science and technology in the century.
Optimization and Artificial Intelligence (AI):
Will boost the modeling and simulation codes in the
near future.
Technology of 21 century
