With the rapid development of computer equipment, approximation by analytic
al solutions has become popular in mathematical modeling. Finite element (F
E) analysis uses numerical methods to solve problems with physical phenomen
a, and these can be applied to various geometrically complex materials, suc
h as brain. The FE formulation can provide such diverse domains as heat con
duction, torsion of elastic material, diffusion and fluid flow, and it can
view different objects of study in the neurosurgical field. In this article
, the various applications of FE methods are introduced to illustrate the u
sefulness of the technique and the Link between the external biomechanical
aspect and internal phenomena in brain research.
