Coarse sphere remeshing

Author: Vicente Mataix Ferrándiz

Kratos version: 7.1

Source files: Coarse sphere

Case Specification

In this test case,

The following applications of Kratos are used:

• MeshingApplication with the MMG module

This is a very simple remeshing test, where we remesh a coarse sphere with MMG library.

In this problem we remesh using the gradient of the distance function, which is the distance to the plane contained in the sphere center. The function can be seen in the following figure, corresponds with a linear distance and a constant gradient:

With the following result:
