Computational Fluid Dynamics (CFD) is a tool being 
extensively used in research as well as in the industry 
for solving complex fluid flow and heat transfer 
problems. Simultaneous development of high performance 
computing (HPC) technology, numerical algorithms, 
physical and chemical models of flow physics, etc. are 
responsible for the big impact of CFD in solving both 
basic and applied scientific and engineering problems. In 
recent past, CFD has developed into a rich and diverse 
subject and has emerged as a major component of applied 
and basic fluid dynamic research along with theoretical 
and experimental studies. The use of CFD based simulation 
ranges from the analysis of the movement of 
microorganisms to the weather prediction. The leading 
manufactures, like automotive, aerospace, naval sectors 
frequently use this technique for the building of 
prototype and product development.The importance of CFD 
is continuously growing with time with the increasing 
capabilities of CFD and its applications. Recently, open 
source simulations software attracted so much attention 
because it is free of cost and flexible. However, using 
Open source CFD requires additional skill sets. The 
purpose of present workshop is to introduce the 
participants with CFD fundamentals, open source CFD and 
its advantages and limitation along with its use for 
solving a variety of problems.
