Computational and Data-Driven Engineering Mechanics

    What is Computational and Data-Driven Engineering Mechanics ?
    Computational Engineering Mechanics is the intersection of engineering mechanics, applied mathematics and computer science, which is aimed at developing new methods and algorithms for solving computationally-challenging and previously intractable problems in science and engineering.With the advances in computing power, high performance and cloud computing, Computational Engineering Mechanics has become a major component in numerous industries including but not limited to Civil, Mechanical, Biomedical, Automotive and Aerospace Engineering, as it can replace costly and sometimes infeasible experiments with reliable numerical simulations that provide unprecedented efficiency and precision. Furthermore, with the exponential growth of data from sensors and numerical simulations, our goal is to teach students how to leverage the augmented intelligence approach enabled by machine learning to process this data to make better engineering decisions compatible with physics principles. Ranging from atomic scale simulations to kilometer-scale civil engineering operations, simulations and data analytics covered in this program will enable graduates to predict the response of solids and fluids subject to a range of loading and boundary conditions, which are useful for the understanding of complex phenomena, and can lead to safer, more durable, and sustainable engineering designs.

High-fidelity simulations of virus-laden aerosol dispersion in turbulent atmospheric boundary-layer flow.

Droplets have a diameter of 100 , a settling velocity , and fall relatively quickly to the ground. Aerosols have a diameter of 5 , a settling velocity , and can travel long distances carried by the airflow. The renderings in both panels depict a pseudocolor plot of the wind velocity magnitude (black to white) and droplet concentration (transparent<yellow<blue) in a vertical slice through the computational domain shortly after a sneeze event
