# Abaqus Adaptivity and Mesh Replacement
|
|
|
|
## Definition
|
|
|
|
Abaqus adaptivity and mesh replacement techniques change or smooth the mesh to improve result quality, control element distortion, or continue an analysis after remeshing.
|
|
|
|
## How It Works
|
|
|
|
The guide separates three adaptivity techniques. ALE adaptive meshing controls mesh distortion by smoothing a single mesh during a step. Adaptive remeshing improves accuracy by generating multiple meshes outside the analysis step sequence based on error indicators. Mesh-to-mesh solution mapping transfers solution state between dissimilar meshes to support rezoning and continuation.
|
|
|
|
ALE spans behavior between purely Lagrangian motion, where nodes move with material, and Eulerian motion, where material flows through a fixed mesh. It is distinct from full Eulerian analysis, but it addresses the same practical problem: large deformation can make a fixed Lagrangian mesh unusable.
|
|
|
|
## Why It Matters
|
|
|
|
Mesh quality can determine whether a nonlinear finite element analysis remains meaningful. Adaptivity trades extra workflow complexity for controlled distortion, targeted accuracy, or the ability to continue after mesh replacement.

## Connections
|
|
|
|
- [[Finite Element Modeling and Convergence Checks]] gives the reliability frame for remeshing and error indicators.
|
|
- [[Abaqus Restart and Results Transfer]] is the continuation layer needed when solution state moves between analyses or meshes.
|
|
- [[Abaqus Eulerian and Particle Methods]] covers alternative discretizations for severe deformation.
