Advantages

• Can readily handle very complex geometry, irregular shapes.
• Can handle a wide variety of engineering problems i) Solid mechanics
  ii) Dynamics
  iii) Heat problems
  iv) Fluids
  V) Electrostatic
• Can handle complex loading
  • Nodal load (Points loads)
  • Elemental load (Pressure dependent loading)
  • Time or frequency dependent loading.
• Can handle objects composed of different materials easily.
• Materialo, cost, time saving.

Disadvantages

• FEM obtains only approximate solutions.
• FEM has inherent errors.
• Mistakes by users can be fatal.
• A powerful computer and reliable software is a must, this increases initial investment.
