Computational methods refer to the use of mathematical algorithms, models, and simulations to analyze, solve, and predict complex problems in various scientific and engineering fields. These methods involve the utilization of computer software and high-performance computing to perform calculations, data analysis, and simulations that would be impractical or impossible to do by hand. Computational methods are used in a wide range of disciplines such as physics, chemistry, biology, engineering, economics, and social sciences. They can be used to analyze large datasets, simulate the behavior of complex systems, optimize processes, and design new materials or structures. Some common computational methods include finite element analysis, computational fluid dynamics, Monte Carlo simulations, molecular dynamics simulations, and machine learning algorithms. These methods are constantly evolving and improving with advancements in computer technology and algorithm development. They have become an essential tool for researchers and scientists to better understand, predict, and solve real-world problems.
