Civil engineers design, develop, and construct community projects that serve the general public such as roads, bridges, damns, tunnels, water supply systems, etc. The designs include but are not limited to many fields such as hydraulics, thermodynamics, or nuclear physics.
A model analyst develops models to help visualize, observe, and predict complicated data. Model analysis is the process of taking large amounts of data and separate it into a structure that makes it intelligible to the binary process of computers.
At the core of scientific visualization is the representation of data graphically - through images, animations, and videos - to improve understanding and develop insight.
