Labs and Projects
The course involves
computer lab works utilizing ANSYS, a commercial finite element code. The
labs are designed to introduce practical aspects and applications of FEM.
Labs include modeling and solving boundary value problems using finite
element method. Approximately eight labs and two projects will be assigned.
Projects are similar to labs, but more demanding.The
purpose of this Lab is to provide student with basic understanding of finite
element analysis process. By using FEA software ANSYS, student will learn
basic principle of finite element modeling and simulation.

How to Succeed
-
Accept that it is
your responsibility to learn the material (in spite of the book or
teacher)
-
Show up and become
engaged with the topics
-
Do the homework daily
so you can ask questions in class
-
Use you resources for
help (classmates, upperclassmen, faculty, the library)
|
