# What is Remeshing?

## What is Remeshing?

Remeshing is a technique that automatically rebuilds the geometry with a more uniform topology. Remeshing can either add or remove the amount of topology depending on a defined resolution. These voxels are assembled around the mesh and are used to determine the new geometry.

**What is Remeshing in FEM?**

What is meshing? In Finite Element Analysis (FEA) the goal is to simulate some physical phenomena using a numerical technique called the Finite Element Method (FEM). So in FEM, we create a mesh which splits the domain into a discrete number of elements for which the solution can be calculated.

**What is adaptive Remeshing?**

The goal of the adaptive remeshing process is to approach or reach targets on selected error indicators for a specified model and its accompanying load history. See About adaptivity techniques for a comparison of this process to other Abaqus adaptivity methods.

### What is DynaMesh ZBrush?

DynaMesh is a tool in ZBrush that allows you to change a model’s shape and then immediately recalculate an optimal topology for the new mesh. Working with DynaMesh removes many restrictions, letting you change your model’s shape drastically, cut it apart, or reassemble it into different seamless configurations.

**What is discretization in FEA?**

The process of dividing the body into an equivalent number of finite elements associated with nodes is called as discretization of an element in finite element analysis. Each element is associated with the actual physical behavior of the body.

**What is meant by meshing in FEA?**

Meshing is one of the most important steps in performing an accurate simulation using FEA. A mesh is made up of elements which contain nodes (coordinate locations in space that can vary by element type) that represent the shape of the geometry.

#### What is adaptive meshing in Abaqus?

The adaptive meshing technique in Abaqus combines the features of pure Lagrangian analysis and pure Eulerian analysis. This type of adaptive meshing is often referred to as Arbitrary Lagrangian-Eulerian (ALE) analysis. The Abaqus documentation often refers to “ALE adaptive meshing” simply as “adaptive meshing.”

**What is Abaqus sweep mesh?**

The swept meshing technique involves two phases: Abaqus/CAE creates a mesh on one side of the region, known as the source side. Abaqus/CAE copies the nodes along an edge, and this edge is called the sweep path. The sweep path can be any type of edge—a straight edge, a circular edge, or a spline.

**How do you use ZBrush ZRemesher?**

The quickest and most simple way to retopologise a model is to use ZRemesher. It is as simple as telling ZBrush how many polygons you want and clicking the button. Find it in Tool > Geometry > ZRemesher. The input number is in 1,000s, so if you put five you will get roughly 5,000 polygons.
