What is the Meshing in Finite Element Method?
A mesh is a network
of line elements and interconnecting nodes used to model a structural system
and numerically solve for its simulated behavior under applied loading. First,
computational techniques create an analytical model by populating the material
domain with a finite-element mesh in which each line element is assigned
mathematical attributes (axial, bending, shear, and torsional stiffness, etc.)
which simulates the material and geometric properties of the structural system.
The system is then restrained within boundary conditions and subjected to mechanical
or thermal loading. The numerical solution
may then resolve structural stresses, strains, and displacements.
Notable meshing
features include the ability to:
- Merge independently defined meshes among frame, shell, and solid objects.
- Coordinate tessellation with object-orientation.
- Observe material boundaries to establish effective aspect ratios.
Tips:-
- Mesh size should be decreased through a series of analysis iterations until two subsequent sets of results are similar, or until the balance between accuracy and analysis time are acceptable according to engineering criteria.
