what is scope for CFD.? is it better than CAE and CAD.? please explain

CAE means computer aided engineer and CFD means computational fluid dynamics in case they deal with field problems which contain both fluid and solid structure related problems and CFD deal with only fluid



A CAD program is a computer technology that designs a product and documents the design phase of the engineering process. CAD may facilitate the manufacturing process by transferring detailed diagrams of products materials, processes, tolerances, and dimensions. It can be used to produce either 2D or 3D diagrams, which can then be rotated to be viewed from any angle, even from the inside looking out.

Computer-Aided Design is the use of computer systems to assist in the creation, modification, and optimization of design. This is often considered an engineering software program.

The program is used by:

Architectures

Civil Engineers

Electrical Engineers

Facilities Manager

Interior Designers

Mechanical Engineers

Structural Engineers

Manufacturing Engineers



CAE includes:



Basic Mechanics

Basic Mechanics

Continuum

Solid Mechanics

Resistance of Materials

Science of Materials

Fluid Mechanics



So depending upon your interest you can choose which is better for you because these course cater somewhat different interest areas.

Good luck.
