This is one-of-its-kind industry oriented 7-day short term course
that offers unique experience of both the field of FEM and
CFD that covers broad range of topics on FEM and CFD.
At the end of the course, the
participants are expected learn the theory as well as
quality meshing and analysis techniques of various types
(1D, 2D, 3D in FEM, CFD problems).
