2. COMSOL MULTIPHYSICS
COMSOL Multiphysics computes new mesh coordinates on the
channel area based on the movement of the structure’s boundaries and
mesh smoothing.

6. CONCLUSION
Finite element analysis plays an important role in
helping to understand the interactions of the system
under conditions that are simulated to replicate nature
and provides a tool for visualizing phenomena not
possible to be observed using conventional
observation equipment.
