This is a software, where you do lots of analysis such as multi-physics, structural, thermal, electromagnetic, CFD, transient analysis and lot more. But CFD (Computational Fluid Dynamics) is becoming popular now-a-days, this is because that in our day to day lives everything dependant on fluids like port flow simulation of engine, airplane zapping to swimming competition. To increase the winning percentage this gives a chance. The result you all may get as a colorful result. This was my first interest- to get colorful result. But later started working in CFD with all real-world problems. So to solve real world problem your model has to be validated for known values with experiments. Also I would like others to share thesome key features which paves a way, to let other knows.
