Meshing
Finite Element Analysis (FEA) provides a reliable numerical technique
for analyzing engineering designs. The process starts with the creation
of a geometric model. Then, the program subdivides the model into small
pieces of simple shapes called elements connected at common points called
nodes. The process of subdividing the model into small pieces is called
meshing. Finite element analysis programs look at the model as a network
of interconnected elements.
Meshing is a crucial step in design analysis. The software automatically
creates a mixed mesh of solid, shell and beam elements. The solid mesh
is appropriate for bulky or complex 3D models. Shell elements are suitable
for thin parts (like sheet metals). Beam elements are suitable for structural
members.
The accuracy of the solution depends on the quality of the mesh. In
general, the finer the mesh the better the accuracy. The generated mesh
depends on the following factors:
Adaptive Methods for Static Studies
Adaptive methods help you obtain an accurate solution for static studies.
There are two types of adaptive methods: h-adaptive and p-adaptive method.
The concept of the h-method is to use smaller elements in regions with
high relative errors. The p-adaptive method increases the polynomial order
of elements with high relative errors. Click here
